I've dated more average or slim guys. It really doesn't matter to me though. I look for for eyes, smile and personality. I just like whomever I can have fun with and have things in common with. I tend to me more attracted to guys that are tall.
Well I'm too old for a college guy but I do tend to like slim and average sized men. However, I don't date anyone based on their physical shape .. there's so much more to a person. My last boyfriend was medium to large.
