There is a whole thread dedicated to "The Art of Tucking: v2.0" (http://www.crossdressers.com/forums/...f-Tucking-v2.0).
Everything from Gaffs to Glues and tapes.

I've tried the superglue idea but it didn't hold that strong. first visit to the restroom and it all fell to bits. Not to mention the mess i made trying to do it all up in the first place.
I'm tempted to keep trying cause i'm stubborn like that. I know it should work better than it does for me so i'll keep trying until i figure out exactly what it doesn't work.
