I (m18) and my girlfriend (f18) have been dating for over a year now. We have kissed but havent made out yet. We are very shy people and so everytime theres been sexual tension we always just start to laugh. Before we went off to college we talked about sex and agreed on waiting. I was thinking about it and I realized that I want to start doing more intimate things. How would I bring this up in a way that I wont be pushy but like still put the idea out there?
