I'm 17 and have been seeing this guy for a while now and I feel ready to have sex. I'm a virgin and he's not and I'm okay with that but I also feel a little insecure about it. What if I have no clue what I'm doing and he thinks the other girls were prettier or better in bed?! I know I can talk to him about it but I'm just scared to because I don't want to wait any longer and he really cares about me but are my insecurities stupid? Should I just go with it and hope he takes the lead?
