whats the most common one
if you take it in the ass?
No It's actually " how big are your arms?" It's a muscle fetish site so it's guys on there who are into muscles on a woman. Of course it varies to what they like. Some don't give me a second look, they like extremely big and muscular and then others only like some muscle but still very feminine. Personally I think I don't have much to offer except for big breasts, pec bouncing, some shape and conversation and an accent.
