Hi. I have been with my boyfriend for almost 7 years now. We are both 21 years old. I had my daughter almost 3 and 1/2 years ago. Our sex life was great before that, then my boyfriend had sex with another girl behind my back over several months. I know he is truly sorry for what he has done. It is painful for me to have intercourse and it seems like I am never in the mood. The affair took place 3 years ago. we are finding it very hard to get back on track with this problem. I never feel in the mood for sex and seem to carry on without it fine. However I know at 21 I should not feel this way. I just wondered if you had any advice for me. Many thanks.
