If don't wear a condom in a bathtub with my girlfriend and precum comes out can she still get pregnant ?

Very very unlikely.: Preseminal flow ("precum") may or may not contain sperm, and if it did, the sperm count would be very, very low. Then, the sperm have to travel through the bathwater and penetrate your girlfriend's vagina. The bathwater would kill the sperm and vagina's have protective lips (outer and inner) Does wearing a condom mean you were having intercourse? Now, that's a way to get pregnant!
