(Quick Warning- I go into graphic detail in this post so squeamish people might want to look away now)
I'm a 16 year old girl. I don't have any sexual experience, but I am relatively well informed. I have masterbated before but never penitratively (not through lack of trying mind you). After a years long battle of trying and failing to use tampons, today I decided it was time to explore myself better and took a look at myself with a torch, mirror and diagram. It's safe to say the diagram was redundant because I looked so alien I couldn't even identify what anything was.
After moving away the labia, at the bottom of the vulva I came across what should have been my vaginal opening. Instead there was this wall of flesh. I think it might be my hymen, but it's really thick and bulging a little. I think I've felt this wall before when trying to insert a finger or tampon. Fustratingly, I know the opening must be somewhere because I menstruate, but I couldn't see it. I stretched myself more (placing my fingers as far as they would go- just under an inch inside) to try and see below the wall, and I think there was some sort of opening there- but it looks to be sealed shut. Touching it felt very uncomfortable and it wouldn't open. Even writing this- about 20 minutes after, I can still feel a slight pain from where I stretched myself.
A little more context on my prior issues with tampons as I feel it is related. For the past year or so every couple of months I've made a few attempts to insert one (pads are just a nightmare and I really want to end my reliance on them ASAP.) The problem is, no amount of force will put one in. Changing the angle, relaxing, having a bath, using a plastic applicator/ minimum size. None of that works. One time I got very close to putting it in- I could no longer see the tampon itself, but before I could push it in the final amount I passed out. When I woke up I threw up and could still feel the tampon inside me, meaning I'd failed.
I'd just like to stress that my concerns about my vagina aren't aesthetic. I don't really care about any of that. All I care about is my vagina actually functioning as a vagina, and I'm concerned that when become sexually active in the future this is going to cause problems. If anyone has a similar story and/or an explanation I'd be interested to hear it. Thanks very much.
