I have not worn a pad but do use panty liners as part of my tucking process. It helps keep my panties dry when my clitty leaks.
Just this morning I tried a new tucking technique. I take a panty liner and run a length of the stretchy, self sticking bandage material down the sticky strip of the liner and leave a length as a tail. I tape the pad just above my penis, absorbant side in. I tuck my bits away, push the pad over the bits, and pull the tail tightly up the back, securing it with a piece of tape on my lower back. The stretchy bandage material slides neatly into the crack. For the short time I had it on this morning it seemed to fit quite nicely. Tomorrow I will try again and wear it for a few hours to see how it holds.
