I tried thongs a couple of months ago at the suggestion of some of the lovely ladies here. I have been converted! I love them. I find that I have no problems being “ contained” as long as I wear the waistband a little low in front. That also gives you a little extra wale tail. That and the fabric of your outerwear gliding over your posterior is a lovely naughty feeling!
Who doesn’t want to feel a little bit naughty 😈 now and then?
