Does sex complicate things?

Alright. Well I recently got out of a pretty serious relationship and even though I’m not looking to jump into another any time soon I would still like to go out and date and just have fun for the time being. Emotionally, I don’t feel ready enough to be with anyone new at the moment; plus the fact that I just want to focus on my family, friends, and college. Like I said, that doesn’t mean I don’t want to go out and date and meet new people. Well, the thing I’ve been wondering is I want to date and get to know other women, but I don’t want sex. I’m not saying that sex will happen just because I’m out in the dating world again, but am I wrong in thinking that sex will just complicate things if by some chance it ever went that far if I meet someone new in the future? I’m not saying I don’t like sex, don’t get me wrong. I’m a 19 year old guy, sex crosses my mind pretty frequently. But I just feel like sex would just complicate things on so many levels. I’m just not interested in doing anything like that until I know for sure that it will lead into a serious thing or until marriage. Am I wrong on this?
