I cuddled with a guy in bed, we were both fully clothed. He was wearing exercise mesh shorts with no underwear and I was wearing track pants with underwear. He was the big spoon, hugging me from behind (means his penis is facing my butt) while we lay in bed to sleep. There was no sex involved. If he had a wet dream where there was ejaculation and the front of his pants got wet, is there any risk of pregnancy for me? Is it possible for the semen to travel through his pants and into my pants and underwear to impregnate me?
