Hey

I am a male-to-female transgender and I'm looking for any tips on tucking... I usually fail at it.
When I am wearing a tight pencil skirt, I usually get away by wearing those body forming panties. Actually they are for making a better shape of your belly (they're high waist), but because of that they hide my private parts. Nevertheless it isn't thaaat comfortable. The main problem is, that the fabric stripe on the bottom is too narrow for my private parts. I kind of "squeeze" them to my back and the pants hold them. But because it's so narrow, my testicles "ooze out" on the sides... and the edges cut into my skin, which isn't really nice...
So I'm looking for a solution that is more for everyday...
Of course I searched on the internet, but the two solutions are either with tape, which I just don't want to do, or by the "push your testicles into the place they usually came from"-method. But that doesn't work for me either, because... It's hard to get them into that place, and when they are there, you can still totally see some bulges, so it is flat in no case.
So I need a solution that just... holds my private parts back there. I tried some of those gaffs you can buy online, but they weren't really that great... I also tried to cut and resew some men's briefs, so they will hold my private parts back... that was the most useful solution yet. But I still have no perfect model and because I have to cut some part of the briefs away, there isn't enough fabric on the edges and they cut into my behind and part each cheeks in two -.-
I also tried the method, where you use the waistband of some underwear with a tube, that you cut off a pair of socks... also doesn't really work...
I know I won't find anything which is 100% comfortable. But isn't there any method, which will hide my private parts without cutting into them, without me having to rearrange them all the time, and which will make my front just flat?
I hope you can help me out...
Thank you for reading my post ^^
