I am a 26 year old female and am dating a 22 year old male. He is very mature for his age and has been in his career for 6 years now and is at the top of his career ladder. He works very hard and does a minimum of 55hr weeks up to over 70hrs a week and has been that way since before we started dating. Work has always been his life and I respect that but our sex life has significantly changed for the worse. When we first started dating (6 months ago) it seemed like everytime we saw each other he couldn't keep his hands off me and we had sex multiple times a day. Now we live together and are very much in love but I'm lucky if we have sex once a month!! I have no idea what happened and I know he enjoys sex with me and I with him but he says he's always tired and has been like this and has always had a low sex drive but if this is true why would it be so crazy in the beginning?? I actually had to tell him we were doing it too much and I was starting to hurt from too much sex in the beginning and now I feel like I have to beg for sex! He's the sweetest, most affectionate guy I've ever met but I'm just not being met sexually anymore and it's really frustrating! It bothers him a lot that I don't orgasm every time we have sex but I've told him that I still enjoy sex with him I just can't orgasm (probably due to sexual abuse as a child) but I can't control it! Is that maybe the reason? I know he has every reason to be tired but he is never in the mood even after having the weekends off from work. I almost feel like he wasn't being real in the beginning because how would it change so much? I would think a guy his age would be just as crazy about sex as I am but he's just not :( do you think he's masturbating or cheating??
