So earlier in the day, I maturbated at around 9 am and took a shower after that. I don't think I peed after, but around 3 my girlfriend and I had unprotected sex for about 3-5 min and i didnt come. I read that after you ejaculate the first time and you don't pee then there's still some left over in the urethra ? How high is the possibility that my girlfriend can get pregant from the pre *** ?
