how do i do it??????????

I want to do full dress now a nice thong and real sissy stuff,however I don't know how to tuck my bits and pieces away.
I have a real small cock which I can tuck down,but my balls are quite big and I don't know how to tuck them away.
ive seen loads of tranny's and you would not think they had anything between their legs,but out a big cock and balls pop,how to they disguise it??? is there a technique to it??
please help.
