Conflicting sex drives

Michaela
So my fiance and i are at odds about how often we have sex... He's dtf like all the time while I don't care to have sex that often. Because of this he thinks I'm cheating sometimes or even because I'm bisexual that i just wanna have sex with a female instead, but neither of those are true. I try compromising like doing it anyway just because he wants to...but if I say no it's still a huge problem. And I'm still very much attracted to him, I love him but I don't like sex as much as I used to....maybe because we overdid it?? Idk, I'm not really sure what to do about this whole thing
