I generally just lurk on this site, but the questions seemed too specific to me to not answer. So here it goes:
1. Definitely not
2. Absolutely. Despite having many friends I rarely allow people to get truly close to me. It takes a lot of work on their part to get to my core.
3. Yes. I wouldn't allow anybody to hug me from as early as I can remember till my late teens.
4. I have been masturbating since as long as I can remember (earliest proven memory was 4 when my grandma caught me lying prostrate in her coat closet moving my hips side to side. She caught me twice. My parents have also told me I was a strange baby/toddler because I always wanted to be lying on my stomach alone). I masturbated an average of two times a day for my entire life (4-23).
5. I am asexual. I am recently married and thought I would be able to have sex when the time was right, but found out on my wedding night that I was completely terrified of the idea. I started hyperventilating and getting sick just thinking about it. Still haven't gotten past that.
6. Yes. I do what my wife and I call, shutting down. When things turn to stressful I mentally check out.
Obviously, there are many different ways and reasons that people become AB/DL. However, given my particular circumstances I have always wondered if I had experienced a repressed CSA. I'll probably never know for sure, but the OPs story definitely struck a chord with me.
