My girlfriend and I had sex, and I came a bit into the condom (as in I pulled out to try to stop it and just a tiny bit went into the tip). We decided to keep going, and when we finished I checked the condom to see if the outside smelled like semen (as I always do as a cautionary procedure), but she had given me one of those flavored ones, so all I could smell was overpowering orange and latex. She isn t on the pill, so would it be advised to go with planb?
