A question about super niche fantasy

My turn-on or my fetish is not common and super niche. And it’s my best thirst trap.

I get turned on when women tease their bare legs on the bed, like one of their legs spread when they kneel on the bed, the leg is bent and the lower leg tucked behind the thigh, and the lower leg and foot is not seen at all.

I mean, their thighs kinda look like “triangle”. Also the knee is pointy. And I get turned on by how that thigh looks “triangle” and that knee sharp, because it gives some kind of mystery that I don’t know and it looks kinda aesthetic. Also I love how women made their legs as “triangular” on the bed.

And I rather see these legs like that, rather than fully revealing (like revealing feet) on the bed. Only a thigh tapers down to sharp knee, creates a triangular shape on the bed when women bend their knees / kneel on the bed, that’s it, nothing else.

Also I love to fantasize women celebrities with hot legs on the bed like that, in their music video clips, social media posts or magazine photoshoots.

I have questions:

Do I have a normal, niche fetish?

Is it normal to fantasize women celebrities on the bed like that?

Is it a doable thing with my partner?
