No Sex🙄

I’ve been with the same guy for almost 5years now. We’ve had our fair share of breakups & makeups & only in the beginning or during breakups were we intimate. It’s going on 6months since the last time we’ve had sex (this is the longest ever). I honestly don’t think it’s because of someone else but just not sure what I’m suppose to do🤷🏻‍♀️ when I try to bring it up he just doesn’t want to talk about it, or says “only girls keep track of that kind of stuff”. I use to complain about it but its to the point now where I just don’t say much about it or try to satisfy myself (he doesn’t know that). I just know this isn’t normal & im only 22years old...I can’t stop having sex yet!

How do you talk to him about it?
