I dont know what to do, me and my boyfriend have been together for a year and we started out great. But about five months ago my boyfriend went off sex completely.
Whenever my boyfriend tries to penetrate me, it hurts. To the point where i am complaining about the pain and asking him to stop. My vagina seems to be too tight.
He was really underderstanding to begin with, and didn't like seeing me in pain... but it's got to the point that when he tries to penetrate me, i start to cry due to him not being able to enter me.
The situation is really getting to my boyfriend too as he seems to have completely lost his sex drive. He finds it difficult to get erect when with me.

I don't want this to cause psychological problems for my boyfriend who i love very much. I just want this problem sorted out.

I am 22, my boyfriend is 24.
I have no other problems, apart from slight discharge sometimes which is a yellow colour, with a faint unpleasant odour, is this normal? Or could it be something wrong?

Please help.
