Hi I'm 18 and having trouble in my relationship because I have little if any sensation in or around my vagina. I have never had an orgasm and very very rarely . Even rubbing my I feel very little sensation. I have bought sex toys in the past to see if that would work but it never has. What's wrong? And how can I fix it?

Go to the doctor, he/she only can give you a correct reason for what is happening. And even can give you a good solution. :)
