And it's damn annoying!
I have some lovely leggings and pencil skirts and I want to be able to wear with standard tops as well as tunics, but I get a pesky bulge when I tuck. I have no plans to start HRT so reducing their size is out of the question, as is pushing back the area as that will be agonising. Apparently, some well-placed padding can hide the area.
Anyone managed to deal with a similar problem?
Everybody's got a different situation down there, so there's no universal advice. You just have to try different methods until one works for you. Success varies according to the garment as well. You may need to use a different method for various clothing looks. The pantyhose method in the Susan's Wiki is good. Doubling up smallish panties works well, but I find it kind of uncomfortable. I've got an older Vicky's Secrets control panty that usually does the job for me.
Do a search of this site for "tucking" and you'll have tons of ideas, I'm sure.
