Look I used to worry about this ALL the time, now granted I don't believe I ever fell into the "preppy" category and there is nothing wrong with preppy (not sure what the plural for preppy people is..Sorry) However I have been short all my life, when I was younger I was very into weight lifting (more out of insecurity than anything else) and now that I'm older not so much, what I'm getting at is women like all sorts of men, and it seems to me they mostly like a man who is comfortable with themselves, this isn't to suggest you be conceited, just be comfortable, don't worry so much about what some girls might or might not like. I used to really obsess about this and worry that there was something wrong with me, all it was, was all my anxiety and the such that was really off putting for the women I knew. If it is any consolation I have seen women also all wrapped up in worrying about their looks, weight etc. And all of that worry and anxiety doesn't make anybody look attractive, so just try and ease up a little, I'm confident you have a great deal to offer some lucky girl, just be yourself and relax. It has always been my experience that when you really aren't looking, is when that special girl will show up, and when she does all those worries and concerns will really fall into the background. The fact of the matter is we ALL want to be accepted and want to be with someone who likes us for who we are, we have a tendency to focus on a lot of things that ultimately really aren't all that important. So please don't give up, and just be yourself after all it is YOU they really want to get to know, not what you "appear" to be. I hope this helps you some, and that you can go out and have some fun.
