Hi, Can losing my virginity damage my perineum? After I lost my virginity I became wide open. I'm scared something has happened to me.

I know when women give birth, sometimes their perineum gets damaged and it causes a "gaping vagina" that requires surgery to repair. But can this be caused by losing your virginity?!! Even when my legs are together my vagina is wide open. I can fit a finger in there almost without touching my vaginal walls!! I 'CAN close it with the use of muscles but after I relax I can feel it opening. I often "queef" because air gets inside of my vagina when I move around. I've seen other women's vagina's and their holes are always closed even with their legs open.. I'm afraid my perineum has been damaged :'(

My doctor says its normal for young women and it will go away, but I don't know how something like this can just "go away". Did this happen to any one of you women out there! Please help me.
