Are you asking 'where' to get them? .... or if anyone 'wears' them? If first one, any adult/sex shop, ... if second I am having a laugh coz you make it sound like a pair of earrings or something.
Sounds hot! My wife wont do it though. Shes too worried about what to do if she has to take a shit while were out or whatever. Ah well.
I've worn it for my bf while we had company. It turned him on immensely knowing that I had it in my ass. I had to come into the house for something and he followed me..Pulled me into the bedroom and locked the door...He pulled down my panties and fucked me while the plug was in my ass..He was so turned on that he came in minutes.
