Feeling sexually undesired

I (26F) have been with my partner (31M) for 7 years now. We’re very compatible in almost every way we’re both ambitious, we share similar family values, and we want the same things out of life. That’s why this whole situation frustrates me even more.

I feel really sexually frustrated. He has an extremely low libido, and we’ve talked about it multiple times. He never takes initiative, he rarely seems like he’s enjoying himself when we do have sex, and honestly, it sometimes feels like a chore to him.

Because of this, I’ve found myself getting attracted to men around me, watching more porn, and masturbating more, which also makes me feel guilty. Sometimes I even miss my ex, even though we were very incompatible in other areas. My ex and I used to have meaningless sex multiple times a day, and he made me feel desired he complimented me, made me feel sexy, and always made it clear he wanted me.

Now, compared to when I was with my ex, I’m much better looking and thriving in my career , a lot of that thanks to my current partner’s support. So it makes me feel like I should be even more desirable now, but the sexual mismatch makes me feel like I’m not. AITAH for feeling this way?
