There are several options here:
1. Gaff – basically a super tight panty that just sort of smashes everything down
2A. Tape Tuck – This is the one you’ve probably come across. Moving everything in place, then taping it down so it stays put
2B. “regular” Tuck – This one is the same as the tape tuck, but without the tape. Sometimes people use gaffs and/or a pair of tighter panties to hold everything in place. Requires some adjustment once pulling everything back on after using the bathroom.
3. Glue – Similar to the others, a bit more… long term
the regular tuck is good enough for sort of daily/simple use. Tape is really only useful if you need to make sure you stay tucked for a longer time and/or you’re wearing really form fitting stuff that you want to be sure won’t move around.
Gaffs can get a bit uncomfortable after awhile from what I understand
