My girlfriend and i were having sex for the 2nd time in one night and i didn't realize the condom had broken. I didn't come the 2nd time but should i be worried of leftover semen from the 1st time? It's not like i used the same condom or anything and I know I didn't come but i'm still very worried. I think i'm going to go get her Plan B just in case but I'd like to know all the same. Thanks.
