Guys, what would you think if your girlfriend did…?

So if you two were making out and she put her thumbs inside the top of your jeans but not your boxers and then kinda grabbed your belt, what would you think she wanted?

And also, is it weird that my boyfriend and I havie never just kissed, weve only made out and weve been going out for a month and a half?

Im 17 and hes 18 if that makes any difference.
