Assuming you've exhausted common tucking tape products, I have a couple techniques that work well for me.

Have you tried combining tucking with gaff underwear? Works well enough for me, but like any tuck, it can come undone. But the gaff can help keep things flat enough until you get a chance to re-tuck.

For tapes, Mefix tape and 3M micropore tape are commonly used for T-taping in the foreskin restoration community, so it may be worth trying as an alternative to other tucking tapes
