My partner and I have become intimate and he started rubbing his penis in my vagina. He placed it in the entrance of my vagina but did not really pushed it forward cause we don't want to go to that level yet and I'm still a virgin. I am worried because he ejaculated in my mound but he wiped it immediately with a cloth. After several minutes I asked him to check if the hymen is still intact and he did it by feeling it with his fingers. I read that there's a chance you can get pregnant by fingering if there's still live sperm attached to the fingers after ejaculation but he wiped his hands with cloth and washed it with alcohol after he ejaculated. It's been 2 days since that happened and I also wanted to know if there's anything I can do to prevent pregnancy even after having unprotected sex. I'm not on the pill or any contraceptives.
