Tucking is one of those things that we just have to do. Love it or hate it. It will get to a point where tucking will be as routine as putting on your shoes. I usually tape, but if I'm wearing jeans or something loose fitting I just tuck it back with no tape and let my panties hold everything in place. I've been on hormones for quite a while and tucking in the testes gets easier as they shrink a bit on hrt. I have Trans girlfriends who are very small and they don't have much to tuck and that can cause problems too. I am quite cursed? Gifted? Depending on your perspective and my testes are very atrophied from t blockers so tucking for me has its challenges but over the years I can tuck in almost anything. Hang in there, it does get easier. Also don't stay tucked all the time, at home I keep everything up front but for some who are dysphoric this may be difficult.
Thanks,
