Apparently I [27f] was doing a ‘sexy baby voice’ on Zoom and now my bf [28m] is upset

I work from home, and my bf was in the room while I was taking a call. His ears perked up as I started talking, because according to him, I was talking weirdly.

In my mind, I honest-to-God was just speaking normally and was trying to give affirmation in a confident and reassuring way. I had been giving affirmations such as ‘mm hmm’ and ‘yeah’, which my bf thought sounded like sultry moans. I also apparently changed my pitch to go lower and my tone gentler. I make my voice like this sometimes because I’ve trained as a therapist and this is how we’re taught to speak. I was on call with a man and a woman, but the man was the main talker, so I was mostly addressing him. No one on the call flagged anything up.

Now my bf is upset because he thinks I have this subconscious thing where I try to talk in a ‘sexy baby voice’ to men. I’m not sure whether he’s right, but now I’m sure as hell gonna try to speak in a flat monotone voice whenever I’m speaking to men to avoid coming across as flirtatious. Has anyone else experienced something similar? If so, any advice please?

Tl;dr - My bf thinks I have some subconscious complex where I attempt to speak in a seductive way to men, but this is really not my intention at all. He’s upset with me now because it feels to him like I’m being unfaithful to his face, and I don’t know how to approach this.
