Gaff is the usual term for these, and yeah that's what I came to the comment section to mention too. If you can't afford one (anyone reading) then Point of Pride has a program to get a free one: https://www.pointofpride.org/free-femme-shapewear

gaffing tape sounds painful, but strangers on the internet know best.

Oh god no! Not tape hun, that sounds awful. They're a style of compression underwear. Think a binder for your junk: https://origamicustoms.com/collections/compression-gaffs

Edit: Origami Customs is also the company that partners with Point of Pride to provide the free gaffs I mentioned in my previous comment.
