@anon, your words are very much appreciated... it's good to know that I've got someone rooting for me!

Hopefully it all pans out.
@jeremy, I guess I would have said that I might have been somewhere on the asexual "spectrum" but it's hard to tell. I'm also an anxious/insecure type in general - so is it possible I was just too insecure to imagine sex with people? IDK. I jerk off a lot, like up to 3 times a day at certain periods, so I don't think I have a non-functioning libido, and I did find guys hot, so I'm not sure. For the time being, I'm progressing "as if" I have a sex drive to change, and we'll see where it goes.
I'd also be interested to hear if you listened any more to Male Sex Animal!

OK, so first in-the-wild effect. I was at college today and this girl was telling me about how she'd gotten a ride home from this guy in our class, (good friends with this girl) and he'd fingered her before driving her back, and she was acting all giggly about it, and I found myself getting like BIZARRELY jealous of the guy and wishing i'd been the one to get that chance. Then I kept noticing her ass whenever she was walking in front of me, and how nicely shaped it was. First time happening!
