I suffer from vaginism

I am a young woman, 24 years old and I suffer from vaginism. Medical check-up showed that physically there is nothing wrong with me.

I had some appointments with the doctor and she referred me to a sexologist, but I do not dare to go yet.

I read on the internet that it can have to do with negative messages about sex from parents to children. My parents never talked about anything, so definitely not about sex.

The worst thing is that I am too afraid to start something with a man, because I'm scared that I feel freeze and it is super difficult for me to talk about it.

I hope that somebody has some experience or some tips to help me on my way?
