So me and my gf were dry humping and my penis was outside my boxers and she had thin pants on. While dry humping I came and my penis head was faced towards me and it got on my shirt and on the left thigh area of her pants. She got up and changed her pants she said it felt as if sperm seeped through and it was on her thigh a little close to the vaginal area but more on the lower side of the thigh. She wasn't wearing underwear underneath the pants. She said she was super dry though and not wet because it was irritated since the pants were rubbing against and she said she was super dry. She had her period on 3/31 and this whole incident happened yesterday 4/7. Could some sperm possibly have gotten in and could she get pregnant? I'm super worried. She's also a virgin and so am I. No penetration
