I've made a pair of tights, with an outside hulster, for the cock and ballsack.*S*
The point is (partially) that it is a ladies-model, as there's no need
for room, for the genitalia inside the tights..*S*
Finally I've succeeded in creating a sewingpattern, for the cock'n'ball-hulster,
since this is not something you'd find in the usual sewing magazine !
I've made a scan of the cutting pattern, with a piece of paper, with 5 x 5 millimeters squares, in order to let you print the pattern i the right size.
You'd probably need to correct the pattern to fit your size, but now you've got the 'raw material'
How-to:
I've also made a pair, in 'bathsuit-fabric' -in two colours..*S*
