My technique is based off of Trinity "The Tuck" Taylor's technique! I don't use the spray like her though, so I use more of the tape! Keep in mind this is for really tight tuck! The tape is incredible for Sensitive Skin, but make sure you remove any and all hair down there!!! My penis is a bit below average size of caucasion men. Sometimes I'll use a piece of fabric I cut to seperate the tape from my skin. I cut the tape first. I measure to my dimensions. Be sure you do all of this in front of a mirror! After I push my balls in, I take as much of the skin from my scrotum as I can, and almost like a hot dog, I pull back my penis just enough to use regular medical tape to wrap it, which keeps it all together and also makes retucking easier. I also put a little bit of tissue on the end of my penis incase I leek or get excited. Then I pull back my penis as far as I can, which helps keep it in place. If I'm wearing something that doesn't require a tight tuck, at this point I'll just put on my gaff, and some extra undergarment for security and comfort. If you need to go tighter, then I put the fabric over my skin, lay the first long strip of clear vinyl tape down and pull tight! I Like to do one right down the center first, then make T's on both ends with smaller pieces. Then I take another long strip and lay is angled towards the right of my pelvis, and then one towards the left. Finally one long strip down the middle. Then unless I'm wearing lengerie, I take my gaff, and pull it up. I take whatever underwear I want to put over, and n BAM!!! No one would ever know, except you! I recommend starting this gradually, so you can build a tolerance. Start 2 hours a day then increase 1 each day. After untucking, this tape doesn't leave residue btw, I usually relax without anything on, to let everything settle.
