we just used a sex toy earlier and i noticed right in the middle that i was bleeding. it was pretty dark. it scared me and i had to run to the bathroom. i washed myself off and waited a couple minutes to check if i was still bleeding and when i wiped off there was no blood but i'm still worried. having some discomfort down there but bleeding stopped. should i be worried? if it was already clean i can't get an infection right? that's the first time that happened. although sometimes when he gets really rough i do bleed a little bit but this time it was kind of alot.
