Fantastic idea!!

Pros-

There is a great Wiki how to article to help you fit, although I will suggest that you go one size down with the manufacturer’s suggested sizes if you’re super tall or skinny (I’m 5ft8 and skinnier than shit). I bought a Mueller “hard” cup, typically used for full-contact sports like football and rugby. The great part about most of the brands now have sizing on the back of the package.

The specific reason I bought an athletic cup even though I haven’t had bottom surgery is that I went out rafting with some of the guys and I awkwardly noticed that one of the guys was wearing a cup and I asked him about it (we’re super close), and he said that he has an old one he drilled a couple extra holes in (to drain water) because he’s been hit really hard before while swimming and almost lost a testicle a few years ago, so now he always wears one. It gave me the idea that it’s a cheap, fairly safe way to pack without using a packer while swimming because most packers aren’t water safe and most STPs (Stand To Pee packers) make you look like you have a hardon when you get wet and it’s super embarrassing when people notice. I chose a cup a size smaller than suggested because I am super skinny and as I stated before, I don’t want to look like I have a hard on.

Cons-

You may have to try a couple out in the shower moving around to see if that particular cup will cause a lot of chaffing in the groin area.
