I'm not too sure how many "ass girls" there are here. But I want to know why you like boy booty (aside from pegging)

Honestly, as a bi female thats leans towards women.. I can't really sexualize a males body.. Abs, muscles (though being weaker than someone strength wise is attractive to me), even butt.. It does nothing, but woman come so easily

I guess i just like it because its cute, bigger than mine, and since its a 'thing' for straight women to be into them i give the booty attention so it doesn't feel neglected... Its cute, but i dont have the organs to really sexualize butts besides thinking they cute

I like it, on the booty-appreciating-spectrum but not sure whats to love.

Its holdable, slappable, kissable, rimable, huggable! Dude buts comfy cozy lovey dovey

Sorry im not the hardest core asset-appreciator  ( •́ ̯•̀ ) 

Wdym "aside from pegging"?
Every girl I've ever talked to that liked pegging had nothing to do with body features :p
Boils down always to the same thing, which is power/control (some word it more nicely, like "I enjoy how he reacts to me"). Makes sense, as there isn't much of a physical stimulus for women who peg.

Not an ass woman regarding any gender, but a cute butt is never a bad thing.

I just enjoy it the way anyone enjoys ass lol. Like limerance said, asses are squishy, comfy, squeezable, kissable, slapable, holdable, rimable and fuckable! I love both bubbly asses and nice square asses that really show off the muscle definition. I love kissing and licking asses on both genders. I'm super bi so as long as you're a man or woman with a nice ass, you're hot stuff! :D

As a bi girl as well, I'm going to somewhat echo limerence's thoughts. I'll try to describe it as best I can.

When it comes to purely visual sexual attraction I have a significant preference for other women. But at the same time I very much prefer doing the deed with men. When I masturbate, I'm usually looking at how hot a girl is, appreciating that, and also imagining myself in her position.
TLDR:Maybe slightly but not in the same way as girl ass

Well, this site definitely helped me explore my bisexual side lol.
But i enjoy all asses!
Doesn’t matter the gender, size or color, i will bite them all!
