Hi! So, last night, and I apologize if this is explicit, my boyfriend and I were dry humping. I had on sweatpants, but no underwear. He took out his penis, and I was grinding on his penis, with the sweatpants on. I was very wet, and the sweatpants were damp. He didn't ejaculate from the dry humping, and we moved on after that. My question is if I should be worried about a pregnancy risk, despite having a barrier (the sweatpants) between us? Does it matter that they were damp? Thank you in advance!
