I’m on the mini pill so I’m trying to avoid pregnancy. My bf and I decided to have sex and for the first time he came inside me - (we’ve had sex before but used condoms). The problem is that I felt a stinging sensation immediately after he came, and it lasted about 20 minutes. There was also some blood, but I had my period two weeks ago, the blood may be from the friction, but the sex felt great. Is this normal? Has anyone experienced this or know what causes it?
