Hello doctor. I want to know that can sperms go through clothing? Me and my gf were dry humping. We never ever had sex. I rubbed my penis with her vagina clothes on. But she was wearing a leggings which was thin and panty too. I ejaculate in my pants. Ejaculate a lot. I felt wetness on my upper thigh. Can sperm swim through that four layers of clothing and make her pregnant? I am a virgin too. After that she had her 2periods. But I heard that a girl can have their period during pregnancy.
