Me and my girlfriend did some dry humping with our underwear and I ejaculated while doing that. After some time, i did some anal rubbing(no penetration) without clothes and I came on one of her buttocks and cleaned it with tissue right away. She also went to washroom to wash herself. I have a doubt that's making me anxious, • Does my precum contain any sort of remained sperms from the previous ejaculation?? • Can she become pregnant even tho there's no penetration ?? She has irregular periods and 40 days cycle in june month. We did it on 15th day of her cycle on july 5th. Please help me with it. Thank you.🙏
