Right, so, I really hate talking about this sort of thing, but I cannot really speak about this with a therapist, because it would reveal my TB/DLness.
Okay. SO. I have this girlfriend, I love her a lot. She's the first real relationship I've ever had. I'm not overtly sexual about people, never have been. I had my first infantilistic impulses when I was three years old, so it is deeply set in my genetic makeup. By the time I hit puberty, it was not about girls or guys or anything - it was about diapers. So, now that I have someone who I'd like to be sexually involved with, the main barrier I have is that, though I am able to... ahem... 'get arroused', the climax part of it doesn't happen as easily because physicality is not my main thing.
So is there anyway around this? I love her so much, and I have no problem making her happy in that regard. But she keeps thinking there's something wrong with how I look at her, and that's the reason why I don't 'finish off' as well. I'd like to tell her a little more about my reasons, but I know that she thinks that furries are weird. So I know she'll think infantilism is weird too.
