Intimacy Issues in Boredoms

So, Allison and I have been seeing each other for over 3 weeks now. We hit the ground running, already at 3rd base from the beginning. Now there’s something off with me, though, and I don’t really understand what. It’s not the male-standard issue of impotence…it’s not really a physical thing at all…I just don’t think I want to be sexual. I’ve run a bunch of different theories in my head and my most promising one is that I feel guilty letting her do anything to me. I’ve tried to dissuade her from it but she seems to have an honest desire to reciprocate so that’s not sticking well. Another theory is that my already weak sex drive has finally just died out but I don’t think that’s a thing. My third theory is that I’m just not sexually attracted to her. I mean, I think she’s wonderful and beautiful and she’s a great person. I love spending time with her, I like kissing and cuddling but the sex thing is just throwing me off.

What the fuck is my deal? Seriously.
