Why am I so jealous of guys ??

I'm a girl and I am genderfluid, but I've been extremely jealous of guys lately and I'm now just fully embracing how I'm gender fluid and stuff but I've had crushes on a couple 또는 guys lately but I'm jealous of them and their physical features and I try to ask my 프렌즈 but they just say aren't 당신 supposed to feel like that towards girls? :/ not much help. But idk what to do. I get jealous of their looks and when I feel like they look better than me 또는 stronger than me, ANYTHING really and I don't like this feeling. Any advice?
