Ive been with my boyfriend almost three years. We’ve always had a pretty normal sex life until I got pregnant and that disappeared which I understood to an extent. Then after having my child it took him awhile to get back into it. About a year ago I found out he had cheated on me during my pregnancy with my best friend. He was also have provocative conversations with numerous girls over the internet. I ended things until about a couple months ago. When we started working things out, we were having sex all of the time. Good sex. Now that things have gotten back to normal, sex is a rarity. It’s once every two weeks if Im lucky and he’s not as enthusiastic as he normally was. We’re both in our early twenties and he was pretty promiscuous before our relationship. Im worried that he could be cheating again. He denies it and its something we’ve discussed more than once. Should I be as worried as I am? Or be feeling so rejected? Please help.
