Am I pregnant if he barely rubbed his penis on my vagina? And he didn't cum. And he didn't have live sperm in his pre cum because he peed before hand.

Misinformed... It only takes ONE sperm to get pregnant, and peeing beforehand does not eliminate the risk of pregnancy as you may have wanted to believe. Now, the only way to address your concern is to check a home pregnancy test, and proceed accordingly. If negative, & next time, please take precautions if pregnancy is not desired.
