So I've been googling and reading articles about this but I think I should share my problem since every situation is different. I've been with my boyfriend for about 16 months now and we have lived together for the past year. (Yes I moved in early in the relationship but he wanted it too) anyways we always used to have sex in the beginning. I mean like 2 times a week. Then it started dwindling down. Now we have it maybe twice a month if I'm lucky. He's 21 so he should have a high sex drive. Now let me say our relationship is not perfect. I did catch him cheating and we just got off of a "break". Whether or not he had sex with another girl during that break is something I don't know. He works at a job where there is only males and I know he doesnt talk to any girls since he's never sneaking around to text or call somebody. And there hasn't been any changes. Such as, I'm not the skinniest girl but I've had the same weight the whole relationship. Every time I try to have sex with him, he says "no because I ask him too much" even though I really don't. There's even times when he will randomly say that I'm not getting any tonight, when I'm being flirty with him. When I ask him if its me, he says no he's just tired or doesn't feel like doing it. As for porn, I know he looks at it. May not be every day but maybe three to four times a week. So now that you know my story, pleaseee help me
