I have to say that I have never been able to do any of the tucking techniques successfully, which I deeply resent. After years I figured out what is to be done, and I can certainly place my testes inside the cavities, but they will always drop out of those pockets, sooner or later; I'm quite sure that in my case they need to be taped into place, which I'm not quite happy to do! Perhaps — and I'm just speculating! — some people develop some muscles allowing them to keep the testes inside the cavities, and this might be something you can learn or exercise, but, in my case, I haven't figured out how.
I still try to do my best with a gaff. But in my experience, most gaffs will not work very well. In fact, I have bought many, but just two will work properly to a degree. One advantage I see is that technically you can use a gaff both for "tucking" (i.e. replacing taping/gluing...) but also simply to give your bulge a much flatter appearance, which works quite nicely in my case, and is quite comfortable to wear for extended periods.
But I'm quite sure that the same can be accomplished with tight panties made of a strong material. The gaffs I've bought from online shops catering to CD needs are expensive — $35 or so each. For less than $10 I can buy tight panties on any (physical) shop around here, and all I need to worry about is how strong the material is (the less it stretches in the front part, the better they will hold everything in place). Panties also usually look much more feminine, gaffs are often (not always) purely utilitarian and functional and absolutely unsexy.
On the other hand, a good gaff will last for a long, long while. I have one which has lasted 15 years (the other 7 or
with weekly use
So maybe the high price tag was worth it.
