My boyfriend and I yesterday had sex for the first time. Protected ofcourse using a condom! It wasn't for long because it hurt and I wasn't use to it yet so it was about 15 20 mins we were having sex and at one point when he started going harder we heard a noise but I wasn't worried till he mentioned it because I'm pretty sure it was the way he thrusted and the air pressure that made that noise. He said the condom was put on correctly and when he took it off it seemed in tact also. Oh and the other day I grinded on his dick both bare but it never went inside just between the lips. I know asking this may be stupid but I just want to be sure. I really want to be safer and use a form of BC so which do you guys prefer? I was thinking about the IUD or pill.
