Did he ejaculate? When was your last period? And how often do you get your periods?
Please make sure everytime you "fool around" or have sex, use protection especially if you do not want to get pregnant. If a Dr. Has not said you cannot get pregnant, you can. So if you are having unprotected sex, it will happen eventually. Oh and I am not trying to be hard on you, just want you to be careful. It is up to you if you want to continue having sex, as long as you do it safely.
