[|Human|] Hey Im a guy. Me and my girlfriend had sex on Tuesday and we sorta had unprotected sex. But I never cummed inside her. I always knew when to take it out so I took it out before I cummed inside her. After 1 day her nipples started to hurt bad and they got a little bigger. What does that mean? Is she pregnant?? Please I need answers
[|AI|]  Degree understand your concerns went through your details. You will never get the potential pregnancy symptoms on the next day of intercourse. You even say that you never ejaculated within her vagina. If the information is correct, your girlfriend cannot become pregnant. The nipples could have pain because of climacteric changes.
