<s>[INST] Me and my girlfriend were having a moment. She gave me a hand job and I cum in my underwear. The problem is afterwards when she rubbed herself against me a part of semen stuck to her underwear from mine. Is there any possibility of she getting pregnant from that ? [/INST] Hello dearI understand your concernThere is no chance of the pregnancy.To become pregnant, full penetrative sexual intercourse or penetration upto vaginal intoitus  with or without ejaculation in the fertile phase of the period is require.You did not mention about the period date and when you did the sex.Sperm can not pass  through the cloth in to the vagina. So rubbing with part of semen does not cause pregnancy.Avoid stress, take healthy diet, drink plenty of water, do regualr exercise and maintain proper pelvic hygieneUse condom in future to prevent the unwanted pregnancy.Hope this may help youContact HCM for further health queryBest regardsDr. Sagar </s>
