Being relatively new research, there are still plenty of uncertainties in what has already been studied and learned. Thus far, the information on sexual desire has been gathered by studies relying on methodologies that give only descriptive data (Beck & Bozman, 1995). While the information has helped the basic understanding of sexual desire, there is still a gap between understanding the influence it has on the arousal response and sexual behavior (Beck & Bozman, 1995). The lack of information does not end here. Gender differences are highly under-investigated when it comes to sexual desire as well. Beck and Bozman (1995) have noticed this problem, stating that “many studies assessing correlates of sexual desire have relied on exclusively female samples, thus limiting our ability to understand gender differences in the phenomenon of sexual desire”. That is to say that it's not that men haven't been studied before, as was shown in the previous study conducted by Hale and Strassberg, but that women have been dominate subjects.
	Another problem to note about the research of sexual desire and its connection to anxiety is the use of studies based on Kaplan's research. Kaplan's model of hypoactive sexual desire disorder (HSDD) has been primarily used to study the effect of anxiety interrupting sexual arousal (Beck & Bozman, 1995).
