It's depend on the girl and the boy :)
girls are sexy..
A silly question ..
your profile picture is so romantic.. :)
i don´t know but maybe are the girls.
I think Girls because we have so sexy body ,but not all of us can use their charm.
It depends, boys can be sexy too (like me!!)
For me, sexiness belongs to someone who can handle their self oustandingly in any circumtances. It doesn't necessarily if it's a boy or girl because for me both can be sexy.
