Hello, I Have A Bit Of An Embarrassing Question...I Seem

Hello,

I have a bit of an embarrassing question...I seem to have a very small vagina and it is almost difficult to find. I have always found it too difficult to even insert a tampon as it feels that even when I do find an opening it is a very short passage and almost seems to be blocked? This obviously also makes having sex quite difficult too and I don't know what I should do about it...can you please advise what may be the cause? Any advice would be much appreciated.

Thank you.
