In my experience I have found that most of the time the women pick their men and not the other way around. You gotta be confident, thats true, but you also have to be aware and ready to act when you're being picked. Be yourself bacause if you arent and youre looking for more than just a piece of ass youre just cheating yourself.
At least you got to have sex. I'm in the exact same position minus any previous experience with sex (or dating for that matter). I've been told I'm attrative, and every once in a while a girls will do small things that make it obvious they find me attractive. Their interest is never sustained though because, just like somebody else mentioned, I'm "too nervous to form a sentence." I think nowadays it'd be considered a social learning disability. I also think when I was a kid the existence of such a thing wasn't recognized, so nothing was done. I'll be lonely and have trouble finding jobs when I'm old enough to live on my own, I'm already sure of it. And if you got sex once, I'm sure you could again. Even if you don't, at least you got a taste, and thats more than I can say about myself.
