Heya, Buddah:
I'm not single but I will chime in anyway... I was single once!
I tried, for religious reasons, not to masturbate when I was single. Usually I did OK at abstaining from it -- and wet dreams were certainly an outlet. Sometimes they are creepy, though, depending on the dream. (You know, anything involving Mrs. Howell from 'Gilligan's Island,' or whatever...). jk =)
I still occasionally have wet dreams even now that I am married to a beautiful girl. Dreams are dreams. I don't know what the absence of dreams would indicate, but it might be worth discussing with a counselor, if you have one. I find my counselor to be a huge help while I am dealing with the SA, in many regards. School, sex, whatever.
I think that you are in school, right Buddah? They should have a counseling center there, I would imagine, and hopefully you can find a professional who is a good match.
Hang in there, man.
Kurt
