I want to get my friend to wrestle me, but im worried what hes gonna say.?

We've been buddies for 15 years and were good friends. Occionally we usually joke about whos stronger than who, but lately ive been getting this urge to submission wrestle with him. I do have wrestling mats in my basement and Im thinking we can wrestle down there. I was also hoping I could get him to wear a wrestling singlet when we wrestle. How do you suppose I go about asking him this without coming off as weird? Should I just ASK?
