Guys, when your girlfriend shows off her belly, do you get the urge to tickle her?

Now that it's summer, my girlfriend is wearing a lot of tight shirts and a lot of bare mid-rift shirts. Her belly is very y but every time she lifts up her arms and and I see it, I can't help putting my fingers up to it and tickling her like crazy. She's got a really cute laugh and likes to be tickled up to a point but I wonder if it's too much sometimes.
