Yep! Sometimes it's because he's being gross (e.g., not yet showered, not properly shaven, etc.) or annoying (e.g., taking a joke too far, late on an errand, etc.); sometimes it's because I'm just in a shit mood; sometimes there's no discernible reason whatsoever.

I'd say I'm not at all attracted to my partner maybe... 20% of the time? If I'm feeling that way, I don't bother with sex and neither does he want me to; we both feel like it would cheapen the intimacy for us.

Another 20% of the time, I'm hyper attracted to my partner. The remaining 60% of the time, I'd classify it as mild to moderate attraction where I may not actively be thinking about sex but totally down if he jnititates or there's a ~moment~.

That's how it is for me, at least. Speaking with my friends I know that having waves of attraction and non-attraction is totally normal but if it lasts for longer than a month or two and you can't pinpoint an external reason, then that's when I'd personally start to worry.
