I never had a high sex drive any ways, but recently I have lost complete interest in any sex. I think one of the reasons being that I am taking human anatomy and after dissecting the human body, I feel like there is nothing sexual about it. Before I used to think a penis was beautiful, but now that I have seen what it is like inside, its not that appealing. Same thing with the vagina, before I thought it was disgusting, still do. Does this mean I am asexual now? Any one else had similar experiences?

I don't think it is age related, I am still in my early 20's.
