Okay so I had just got off of my period a day before and my boyfriend and I were fooling around. He fingered me first And then we dry humped without anything on and I felt something cold but it was a two second coldness and then it went away?. I touched my vagina to see if anything was on it and it was dry. After a minute I went and wiped my vagina with a wet cloth.and as soon as I got home my vagina started bleeding. But I'm really concerned about the coldness. Could it have gone inside me?
