different suits produce very different results. I find the best suit comfort wise to wear an enhancing method is a slightly looser nylon or baggy cut spandex suit. If it's to tight then it gets uncomfortable pretty fast.
I'm hung very modestly so always had smaller size suits to keep the pouch snug. When I tried a ring the first time it was very uncomfortable. I ended up using a caussie suit and cut out the liner to give more room and it was comfortable to wear a ring all day. Now I have a few that I've bought specifically to wear with a ring when I don't want to look like I'm hung like a 12 year old
