I've had one for about a year. I don't use it very often but it does feel pretty good. It's kinda fussy to use. Keep it in a freezer bag you can set in hot water for a while to warm it up first or it feels like a cold dead pussy.
Washing it is a chore but you have to do it unless you're a sick mfkr. So, sometimes I'll wear a condom so I don't have to wash it to clean it.
Since it's silicone if you want to keep it from being a sticky mess after you wash it, keep baby powder on hand and talc it up after air drying (drying with a towel will just get the outside covered in lint).
So yea, you're going to have your pocket pussy out for a while any time you use it, increasing the chances of some one seeing it, unless you live alone and have no friends.
