Cheezy-Poofs can do that (as can beer but I wont give up either). I guess as long as you are both comfortable with it and have a great time together it’s fine provided it is mutual and equitable. It’s one thing for a couple to put on 20 or 30 pounds but lets face it; it’s hard to find someone sexually stimulating if they have to bathe themselves with a sponge on the end of a stick.
