I honestly just googled and found this guide to be pretty helpful. I'm not that good at it and don't have any stuff that is specifically designed to support tucking (e.g. a gaff) so it doesn't hold for very long but I think I might change that soon 😅

I've just done so. Thanks for the heads up

In my (transfemme) case it was not tucking an then discovering tucking.

I was always under the impression that it doesn't matter because I'm wearing a skirt that i love and you don't see a bulge with it in any way. But I tried tucking and oh boy! It's not about the visuals but it just felt so much better. Just the feeling of being flat down there was heaven 🤤
