What's wrong with my body???

I've struggled for a long time with this. Sexually things just aren't right. For one I've had very low libido. Almost no sex drive. And two, sometimes penetration is uncomfortable or even painful. And not painful like I'm too dry, because we do use lubricant for that. But it's like his penis is hitting something inside me causing pain.

I've tried different things to boost libido but hasn't worked yet. I just don't know what to do. Wish I knew what was wrong with me.
