I had plans to spend all yesterday writing, but then I got a migraine. So I stayed in bed in the dark instead. Meh.
Woo hooo! Have you named it??
First, welcome!! Second, I think you need to go with what feels right for the character. I have extreme OCD and am borderline Aspie (I'll just
link you to the blog post I did about it, rather than go into detail here). I completely get your character. I can't stand to be touched, except by my husband and a couple different people I dated before my husband--and there are even limits to that. I mean, it literally sends me into a panic and reduces me to a ball of tears when anyone else touches me. I am also very rule oriented, and breaking those rules is
really hard.
From my perspective, overcoming the hurdle of enjoying being touched by someone is huge, and sex is even more huge (I had my own rule regarding sex), so for me it would be realistic to reach that edge and then back off. Realistic as in I did that many times and (full disclosure. I'm trying to get better at this so here it goes...), it probably would have taken me
years to cross that line if I hadn't been raped my freshman year of college. Once that rule was broken once, it was easier to break it again on my own terms, but still a really big deal.
Basically what I'm saying is don't worry about what other people will think about the character's decision, or what you want the character to do. Really think through what the character would actually do, and do your research on Asperger's to make sure you're capturing the character and the traits of the affliction correctly. If you think the character would make that leap, then make sure you lay the right path leading to it. I learned to accept
some touching when I was around 15, but I was 22 before I was actually comfortable with it. I'm just saying, if your character goes from no touching to sex within a few months, I'm going to raise more than a few eyebrows based on my own experience.
