I and my bf were dry humping, he was in his pyjamas and I had had my underwear and shorts, he was over me for a few minutes and then he got off,we both had 3 layers of thin fabric between us. Then i felt my underwear wet, I don't know about his. I did not change though. Its been a week since that and I observed the the around my nipple is growing a bit larger. so am i pregnant? and can sperm pass through clothes at any cost?
