so my gf and i were dry humping for like 30 seconds (she had shorts on and underwear on, i had nothing). there was no penetration but the head of the penis was rubbing against the outside of her vagina (over the shorts and underwear). i didn't cum at all and i dont think very much precum got out. but even then, i'm so stressed that some bits of precum got on the outside of her shorts. idk if it helps but i've peed multiple times since the last ejaculation so i don't think there was any sperm left in the urethra. can someone ease my thoughts a little bit?
