i lost my virginity about a month ago. im on birth control and we used a condom, we have had sex numerous times and i never bled once. i dont think i could have broken the hemen from tampons cause i didnt start using them untill after i had sex due to the fact that i have a very tight opening you could definately say. i also randomly starting bleeding a big lately before i was supposed to get my period about 5 days before. and im on the pill so it shouldnt do this..
