I'm an avid chastity cage user, but have quite some issues with them, since I use them for the opposite reason.

This got me thinking the other day about something I saw ages ago (the ebay store doesn't seem to exist anymore): they made briefs with penis and ball sheaths that looked tiny and were made from 1mm latex or so.

I imagine that if the latex is the right strength it will allow for enough stretch to accommodate the start of an erection but not completely zero, which I'd say is the main reason my penis is slipping out of too flat cages.

Anyway, my questions are: has anyone else had this idea before and maybe tested it, or have I just been unable to find the correct seller for something like this?

Basically I'm looking for flaccid penis sheaths thick enough to supress erections enough to be fun to play with, if that makes sense.
