im going to try and not to get weird..my penis rides a little high,and i cant tuck like most t.g.s,but my groin area has always been puffy and am able to push my penis in and bring my ball sack over the entrance to create the illusion of having a vagina,i wear a size 8 panty which fits me perfect and holds everything in place..i wish they made panty gaffs instead of g string gaffs,but oh well i learned to make do with whats at hand.
