Am I wrong?

So my partner and I have been together going on 4 years and sometimes I can't help but want to be with someone else intimately. Like, I do love her a lot but sometimes I wonder if that's enough. Lately, we've been fighting a lot because of sex and she tells me we haven't had sex in forever, but every time we do have sex I'm always the one initiating the sex. Sometimes I want to be wanted too and I don't get that from her and I crave that. Sometimes I watch other couples interact sexually and I find myself craving that. Like, I want to be touched and fucked spontaneously too and I've expressed that to her countless times, but now I can help but get horny for other women. am I wrong? oh, I'm a woman by the way.
