Girls, do you deliberately try to get guys to tickle you?

My girlfriend loves to be tickled but I didn't know this for a while. She would always walk around with a bare mid-rift shirt and flip flops, and try to draw my attention her belly; either pushing it in my face or placing my hand on it when we were cuddling; or sometimes she would rub her feet against my fingers and giggle. Eventually I took the hint and started tickling the hell out of her. How do you girls get guys to tickle you?
