So I've been with my girl for 4 years.... we're practically married. She's smoking hot and I'm lucky to have her... but her sex drive is out of control. She wants to hump all day long, every day. It was awesome for about the first 3 years.. .but now for some reason I just don't feel like doing it that often. I'm at work and school from 8am to 11pm all week, and when I get home I really don't feel like humping. On the weekend once or twice is good for me and I'm done. She gets real upset when I say “no, I don't feel like it”. It feels like there is this huge barrier growing between us. I can't believe I'm turning down sex.. What the fuck is wrong with me.
