Last week my partner and I had oral sex and I ejaculated on her breast. I wiped it with a clean towel, and we both sleep in the comforter naked. The next morning, she went to have shower and came back to me, and worried that the sperm from her breast might run down through her vagina, and causes her to be pregnant.I don't think she can get pregnant since I already wiped the sperm from her breast with a towel; the comforter should already absorbed any left sperm; her t-shirt that she wore to the shower adds another absorption; and even if the water from the shower hits the sperm and go down along her vagina, it would not go inside hers as the water should fall down due to gravity.But I just want to be sure and don't want to make my partner freak out. Help us please.Thank you.
