I started with larges and moved to XL's in a month. I kept my larges, and I use them for when I want to multitask while noogling (do makeup, laundry, etc.) and when I want to sleep while noogling. Since I'm pretty small, the XL's JUST BARELY fit across the span of my ribs, so I'm pretty limited to just laying down while using them, as they will pop off if I move. The larges, though, will stay on, so they are my "do things in" domes. Even though they don't have the room like my XL's, I still get a decent pull, so I think it's better than nothing. So I say, keep them!
