I feel really dumb posting this but I am 16m, I have been with my girlfriend for just over a month. She is 8 months older than me and a grade above in school. We spend a lot of time together. Last night I kissed her for the first time and she seemed very happy. She is my second girlfriend, I had one about 6 months ago, I ended up breaking up with her because she made me very uncomfortable, asking why I was hard after making out and then getting grossed out, we were dating for 4 months. Anyway my question is, how do I know if, and when, she wants to have sex, and will she want me as the male to initiate it?
