Right, I’ve read about how some women can even experience increased genital blood flow and vaginal lubrication without reporting increased sexual desire.
Some gay men, btw, enjoy receptive sex without necessarily even having erections, while others, even when they do become erect, don’t want their penis stimulated. You won’t see this in porn (because how visually boring!), but sexuality researchers tell us it’s pretty common.
Sexual orientation is so much more complex, I think, than many people realize. Labels of gay, straight, bi, and even pan don’t do justice to the range of attractions and desire that people experience.
