Ok, So is there something wrong with me or what? Me and my boyfriend have been together for 4 months now. Sex was OK for the first part, but he doesn't like me being on top and he mostly likes it doggy style. Lately he never wants to have sex maybe about every3 days or longer. I have a very high sex drive and I like it everyday, or at least every other day. The past month or so he never wants to have sex. He always says his tummy hurts or he's tired (even though he never does anything beside sits on the couch and watches TV or plays football on xbox) He also said he doesn't want to have sex cause he doesn't feel like doing all the work. BUT HOW CAN I DO ANY WORK WHEN HE Doesn't LIKE ME BEING ON TOP or doing the stuff I like? I know sometimes someone can be tired and just not in the mood, but after a few days of being turned down it makes me feel worthless and ty. Makes me feel like he doesn't think I am sexy or something. I don't know what to do? What's wrong with me?

It is not you. It is him. When two people love and care for each other they give to each other. He is selfish as a lover and as a boyfriend. You deserve someone who wants to make you happy. A positive in your life.
As for positions, I have found that men that prefer doggie style tend to be control freaks and demeaning to women (as a variety once in awhile that is not true of the man). They do not like the intimacy of face to face contact because they think of the woman as an object not as a person. These men are unable to commit and you are wasting your time.

AG, You have the wrong boyfriend. It sounds to me like he is using you to satisfy his own lust, not to engage in mutual pleasure.

Find a better boyfriend. :)
