You possibly could have tore her vagina.
It's called a hymenal tag. And yes they can be quite disorienting. I noticed mine after childbirth and began to research it to see if I was "normal" or if it was something to worry about. It is the leftover remains of the hymen which is the piece of skin that keeps the vagina closed or protected until sex or tampons a a girl loses her "virginity". It's purely cosmetic. And perhaps it's only visible in smaller women with smaller vaginas? I'm short 5'2" and have been told by DH that my vagina is small and short too. But I have no factual evidence for this, it is just a theory....
I think you need to be more aware of your girlfriend and her needs I would hate that that sounds really bad
She might have a prolapse. Take pic of it and go see obgyn.
It is probably a little egg-shaped vibrator. Color is usually hot pink with a tail, which is used to remove it.
I'm a 8 inch and thick my wife had two kids. And her vag is way tighter now than before our kids as she can use her muscles. So, how large are you? How do you measure if a vagina is smaller or not? I would just enjoy it. And be lucky to be larger with a smaller one and enjoy how good it feels. Just use more foreplay. Or Lube..
Check Amazon it is a $119 egg vibrator with remote control. If you watched much porn, you'd have seen it.
