<human>: My SO and I have been dating for a little over 4.5 years and have lived together for about 1.5 years now. When we first started having sex everything was great and when we weren't living together things were great too, but once I moved in with him things started to go down hill. 

We have currently hit week 8 of no sex and I don't know what to do. I've tried uping my sexy game, I've tried hinting all through the day that I want to have sex with him, and I've talked to him about it. Every time I bring it up he says that he's too stressed out from work and/or too tired, but that it definitely isn't me. He swears that he still finds me sexually attractive, but I'm having a hard time believing that at this point.

I know that we have different levels of libido. His is obviously lower than mine, which is fine, I can deal with that, but two months of nothing is beyond anything it has ever been. 

Other than that, we have a great relationship. We have fun together, we deal with issues in a calm way, we laugh all the time, and he is my absolute favorite person. I don't want to break up because of this. It seems unreasonable to ask someone to fill my every need 100% of the time, but I don't know what to do next.

Should we go to counseling? He's not fond of the idea, but probably would if I pushed it. Suggest an open relationship?

<bot>: SO and I haven't had sex in two months. Not sure what to do about it or what the best option is.
