Hello, so I’ve been always a little bit paranoid about having sex and getting a girl pregnant, so I always wear a condom, this weekend I had sex with a friend, my penis kept slipping out of her vagina, but I was wearing a condom, came inside her, kept going and came a second time but outside her, I checked it afterwards (filled it with water and checked for holes or leaking) and it wasn’t broken, so me, being the paranoid guy I am, asked her for her period info, so her last period started on Sept. 8 and ended September 11, we had sex on day 22 out of 30 of her cycle (which I read that are ‘safe days’) so what are the chances? Or am I just paranoid?
