For me, experience was more of a deal-changer than size...When I first started getting chances with women, I expected my size to be a big deal; both in terms of their opinions of me and the actual physical experience/activity of sex. Basically, I thought I was going to have to expect different reactions and do different things because I was "so big".
I quickly found out that the first few women I was with said nothing about my size...I was surprised by that. Frankly, I thought perhaps I was not as big as I thought I was.
As time went by, I came to realize that (for the most part) when you are a young guy and inexperienced, the women/girls you are with are just as inexperienced as you and hesitant to say anything because they are also nervous.
The older and more experienced you get, the more you realize the trick to being "good in bed" isn't to be an arogant, self-confident prick or to memorize porn moves: it's to be who you are and to make your partner feel comfortable being with you: whether that means being funny, calm, complimenting, or whatever. Be The Entertainer: show her a good time.
Honestly, a lot of people say "you always remember your first time" or "the first time is the best time". For me, the first time (and a bunch after that) sucked...I was a mess: didn't know what to do, couldn't get hard, acted like an idiot...After awhile you realize it's just about having fun for yourself and making some fun for your partner, and you relax as a result.
As a side note: don't worry about being uncut. I've had a bunch of women be surprised by it but none have been "grossed out" and I kinda feel like I'm not bragging to say that once they started playing with it, they kinda like it because they know it's not gross at all and it's something different: a new sexual experience that they can savor like a feather in the cap...Almost all of the women who commented on my foreskin went from being a bit shocked to trying to play with it and asking me if I liked them playing with it
