Or like something McClaw would wear to church.
I have a nice shock doctor that I never wear. I find it to be uncomfortable. That being said I have been nicked in the nuts enough times to understand why people wear them. You can tell when your rolling with someone who is wearing a cup you don't need to announce anything.
I do notice though I am a lot more protective of my nuts than a guy that wheres a cup while rolling so their maybe some inherit benefit if you ever do have to take it to the street where you won't be wearing a cup.
All and all its really up to you but yeah you don't have to worry about anyone thinking you have a stiffy.
I don't use a cup in rolling. I've always managed to protect the goolies. Touch wood. Pun intended.
Wasn't aware of the cup in comp rule, will have to check it out.
Seriously bro. Wear a fucking cup. It keeps your balls from getting crushed. Why is this even a question. Don't announce you have on a cup because you'll become the "I haz even more kup" guy and everyone will laugh at you every time you leave the room.
Get one you wear with compression shorts unless you happen to enjoy a nice stiff g-string like Arskanator. Plus, the compression shorts will freak out the dudes in the locker room much, much, much less.
Don't be cheap, buy a metal one.
I'll tell a horrifying story (recently happened) involving a plastic cup... tomorrow.
Joking aside, my cup is this big rubber thing that also protects your lower abdomen. You can't grapple with that, it is even annoying to kick with it. And still it hurts balls when you get kicked there.
I don't wear one during judo, but I do wear one when doing TKD. Too many errant roundhouse kicks have dropped many of person sparring.
You guys that wear cups when grappling are...paranoid? Seriously, 30+ years of Judo, no cup, ever, and I fathered two children. And I've been kicked/kneed/grabbed etc. in the nuts more times than I can count. And that was 99% nage waza training/randori/shiai getting popped, not ne waza. It's all still functional too.
and using a cup for leverage for juji gatame is just plain rude.
