i'm 18 and i'm still a virgin. me and my boyfriend were making out the other day but we've decided to go a bit further so we got naked. he ejaculated but not inside me because we did not have sex. anyway I noticed that he did cum when I sat down on his lap. he did have his boxers on and I did not have my panties. now i'm worried if i might get pregnant just because my vaginal area got in touch with that. plus, i was ovulating atm. what are the chances of me getting pregnant???
