Asexual, huh? then why....

Yep. I'm asexual. That means I'd rather have cake than coitus, and that's why I've tried many flavors and varieties of one, but NONE of the other--not even vanilla. So WHY do I write adult-type slash? Because it's art. I like art. I like being creative. I like reading creative things. I like writing creative things. Although I don't have or want personal experience with the subject matter, I do know a great deal about adult behaviors; I've learned about them in my quest to discover my sexuality.
Society expects us all to be sexual. I grew up learning about sexuality. I realized at a certain age that almost all of my peers were sexually active; but I realized that I had no strong desire to join the crowd. It was more than playing safe or standing up to peer pressure; I just flat-out wasn't all that interested. I understood that they had some strong desire for sexual activity that propelled them towards it; but I had one male friend who never ever talked about girls. I never saw him kissing, never saw him checking out the girls, never heard him talking about intercourse or girls with whom he wished to engage in intercourse. As we got older and more girls and boys started engaging in these activities, he became a very close friend to me. It wasn't until we were in our 20s that I found out he HAD been engaging in sexual activities all along--only with boys, not girls. Now that I'm an adult, I realize that there's an even greater expectation of sexual activity by society. Nearly all people my age engage in sexual activity. I discuss it with my peers; they tell me about their experiences. I have decided that most others really do enjoy sexuality, they're not simply feigning interest. They may not enjoy all the partners they engage--some complain that a partner was less than ideal, and other partners were better by comparison; but they do enjoy the activity in general. I don't quite understand why. They tell me "Because sex is fun!" I fail to understand which part of the mating process they consider "fun."
It took me many years between the time I realized that I just wasn't all that interested in sex and realizing that this could actually be a sexual orientation. During that time, I studied a wide variety of sexual behavior. I looked up a good number of male/female positions and fetishes; I watched Kama Sutra lessons (Protip: search for Dr Swayam Prakash on YouTube.). I decided none of them were interesting to me. Then I decided if I wasn't interested in heterosexual activities, perhaps I was gay (that's logical, isn't it?) so I started studying female/female relations. Those weren't interesting to me either. Well, I thought, if I'm not interested in heterosexual or homosexual relations, perhaps I'm transgender! :-) So I started over, checking out male-male relations and male-female relations with the intent of trying to figure out if I were more interested in them if I were the male. That seemed a tiny bit more hopeful in the "appealing" range at the beginning; but in the end, the answer was still nope, I wasn't really interested in that either. Well if I wasn't interested in any of that, what DID I like? I finally realized I was operating under the mistaken assumption that everyone must have some sexual interest; now I have accepted that that is not necessarily true.
My interest in sexuality is now no longer to find my way; I have accepted myself for who I am. I don't like ANY of it. And that's just the way it is. Now, I'm interested for reasons of understanding others and for artistic reasons. I understand sexuality is part of life; but it doesn't have to be part of mine, and that's ok with me. I'm still pretty curious about what others get out of it, though.
