I agree with Maven on this. I would also like to say that if she is experiencing pain she will not want it. From what you said about her wanting to separate might have something to do with this. I'm not saying that she wants to leave you. I'm just saying that I think there is more bothering her then what she is telling you. When I was in my 20's I was very insecure, and this played a big role on my relationship with my husband. (ex now) I'm not trying to sound stupid on this, but have you heard of KY Jelly? This helps a lot. You can find it at Walmart or any pharmacy. If you go to Walmart I think it is by the drug products, or the female stuff. If you know some of her friends maybe they can give you some info about what is bothering her. Hope this helps.
