All rescaled w/in 8-10 attractiveness. Changes take place at puberty. Age only as far as true milf/dilf hotties. If trans, a year-long conscious effort to shapeshift genders or sexes is possible, but only once.

Men trend hard to chubby, muscular, generally bara bodies, with muscleguts, pillow pecs, cute neckfat, and cuddly soft/firm muscles. Body range height 5'10" to 8', weight 180-300lbs.

All body hair increases on scale from x2 to x5 density as approaching low end of spectrum, plush softness, all tight curly, max one inch of puff off skin. Triple beard growth, everyone capable of growing full thick beard.

Women transform into men to the effect of 3:1 population ratio. Men then transform into 1/3 orcs, 1/3 demons. Cultural gender/sex gaps start slowly loosening due to two new "genders".

Metabolic shift: fat and muscle mass can shift entirely on weekly basis. Muscle/fat gain fetishes now extremely easy. Overall nutritional/caloric needs and appetite is halved.

STDs no longer transmissible, retroactively extinct. Fertility/Virility halved, requires conscious intent of both parties to conceive anyway. Libidos triple, inhibitions lower,  public sex acts and nudity fully normalized,  everyday activity. Bisexuality now universal,  with homosexual attraction at least equal to heterosexual,  most common is doubly homosexually attracted.

Anatomy update

Body no longer produces fecal matter,  converts into increased energy.  Anus now lubes like vagina instead, with a sweet taste. Shapes range from normal to donut,  no prolapse. Sphincter becomes highly elastic, both it and inside walls tear proof. Organs are more elastic for big insertions but that isn't likely. Prostate gland doubles in size,  quadruples in sensitivity.

Butts range between big muscly firm and jiggly fat bubblebutts. Men can easily achieve the fattest asses of any current porn star, and they're especially pleasurable to grope and smack around. Its perfectly acceptable to fondle people's asses in public.

Balls increase 2 to 4 times size, randomly, become smooth, plump, soft, resilient and resistant to pain from impact. Pleasure sensitivity tripled. Produce at least half a cup per orgasm, max a quart. A good massage can bring anybody up to a pint for their next nut.

Cum tastes the same with mild flavor variations, but taste buds and the brain now process it as being delicious. Like all the oily, sugary, salty stuff the caveman brain craved is now redirected to cum. It's now a perfect craving killer and essentially full-meal-in-a-bottle once they start realizing there's a big market for cum. Fresh from the tap is always better though.

Cock size increases to min 6", max 18", trend on girthier sizes. Skin is gorgeous and smooth except veins. Sensitivity doubled and skin is faintly lubricated. Bulge groping is also common social practice.

Jaw extension length doubled to easier suck huge cocks. No more gag reflex. Lips and tongue increase in size, softness, sensitivity. Possible to cum just from making out or sucking dick for 15 or so minutes. Sucking someone's dick is a super courteous greeting and you'll make a great first  impression by offering.

Nipples and areola become plump, soft and pronounced. Nipples contain a sensitive core, normally receptive to pleasure from outside, but nip piercings can give direct stimulation which can quickly be orgasmic.
-------------------------------------------

Musk, Cum & Gender update. Applied slow over 2 months.

Pheromone production doubled. Can reach 4x with focused conscious effort to increase output. Olfactory sensitivity can be doubled with similar focus, if you want to be more susceptible. Armpit sweat rate doubled. All body odor now read by brain as pleasant, arousing, and have slow buildup effect of romantic feelings. Like normal, how someone smells is based on how different their immune systems are to yours (I heard), but that's the difference between finding a man who smells great and one who smells like a god. The deodorant industry collapses immediately.

Physical activity promotes musk into a cloud, size and potency relative to the level of exertion. Professional sports are as much an event to see athletes as it is to sample their aromas. Aggressive public sex can lead to a cascade of rutting nearby men. Gyms are orgies.

Humans have by far the most potent musk and tastiest cum, with the most variety of flavors. They also have no refractory period and can produce cum of consistent quality and volume as long as they stay hydrated. With the emerging bottled cum industry booming, humans are perfect milk bulls for high production. Also, they're the most sexually submissive on average and receptive to stimulation on secondary parts: the prostate, nipples, mouth, balls, making them great boytoys as well. Cum bull or sex toy are universal career fallbacks for humans. Cultivate your flavor with a unique diet and some pineapple juice, and you could get picked up as a personal bull to a wealthy cum connoisseur.

Orc's Cowpers glad production is increased. They dribble pre at the slightest arousal and can need catheter pouches in pants to contain leaks. Their preejaculate--and by extension, cum--has a stuporific "himbo" dumbing-down effect. It gives anyone who intakes it (anal or oral) a sluggish, ditsy euphoria, shutting down mental functions and making them only able to focus on sex, exercise and looking hot for their bros. Don't drink too much before you have something important to do that requires your wits about you. It also leads to a misconception that orc's are naturally less intelligent, when in truth, they just sample their own juices very frequently. Also, musk cloud size is doubled.

Demons are the most sexually aggressive gender overall, and the color of their skin reflects their individual personalities. Their eyes are bright and piercing and can induce a suggestible hypnotic trance in anyone staring into them for several seconds. Everyone knows they can do this and everyone has the willpower to shake the trance off, so it's not like they can abuse the power that much. But the trance feels so warm and fuzzy and good, why wouldn't you wasn't to soak in that for a while and just...do whatever you're told? Also, it's rumored demons can sense exactly what turns you on just by your smell. Their cum is exhilaratingly spicy and makes you feel confident, sexy and aggressive.

There are 3 basic types of bottled cum: the tastiest, abundant and flavor-varied human cum, the relaxing, brain-draining orc cum, and the energizing, robust demon cum. Sold similarly to soda pop, alcohol and energy drinks, respectively.

Personally my favorite is a bottle of pure orc pre, teased out by the sexiest lapdances for the most perfect himbo trip. Down it in one go and it'll keep you hard and drooling for days, barely able to think straight for a second without losing focus and searching out the nearest cock. Perfect for a long weekend of being a rutting, illiterate beast, just slutting around and pumping iron.

Women & Misc update

Women aren't left out. The quarter of the population that reproduce are granted doubled size and quadrupled sensitivity to this genitals as well as the same bonuses to general attractiveness, metabolism, nipples, mouths and anuses that men do. Pregnancy time is halved, the experience is months of euphoria and births are multiorgasmic. It does take a little government nudging to maintain birth rates with such increasing rates of gay and lesbian couples. They pump out a lot of kids, but plenty of male couples are in line to adopt.

Female pheromones at close proximity illicit arousal and submissiveness in men, but have neither the potency nor the range of male pheromones. For other women, both male and female musk sparks heightened sexual aggression. And hey, women have increased bust and butt, perfect skin, eternal youth, bombshell bodies and tripled libidos.

Drinking! Alcohol no longer gives hangovers or long-term damage of any kind. Nor does it affect sexual performance or judgement. Dudes can be drunk as hell and still able to get hard, as well as ethically and legally consent to sex. At least, it's no more so under the influence as huffing sweaty human musk, sucking orc dumb-cum or being tranced out by a demon is "under the influence". Regardless, nobody will wake up the next day regretting anything. Pretty much nobody drinks anything but water, cum, and alcohol anymore.

Fashion! While public nudity is perfectly normal, many dudes still wear a semblance of clothing for appearance or restrained teasing. Jock straps, thongs and boyshorts are popular underneath crop tops, muscle shirts, leather straps and tanks. Most everything is cum-proof, but it'll all get slurped up pretty quick anyway. All fashion revolves around slutty club clothes, lingerie, stripper and qorkout gear. And bodies are cold- and weather-proof because that makes sense. Majority of haircuts are varied close fades and undercuts with low mohawks or shaved.

Relationships. Over 50% of male/male relationships are monogamous, but it takes just as much romantic compatibility as normal, as well as perfect musk matching to make the two of them intoxicated and enchanted by each other's bodies. There are plenty of single guys, solo sluts and a range of polyamorous relationships, sometimes looking more like a mass commune of lovers coming and going. Sometimes whole apartment complexes can be one single committed relationship.

And committed all these relationships are. While it's fun as hell to be a complete man whore, most men start craving emotional intimacy,  clear interpersonal communication and comfortable stability. Whether it's one man or a dozen, a sense of cozy and reliable domesticity is the ultimate aphrodisiac.

Women generally accumulate harems around them of the most straight guys left. But it's tough out there, a lot of dudes can get just as much lovin' out there with each other, if not more.
