men and women
I wear it inside of my underwear. this gives me more supprot and somewhat comfortable. I just wear the jockstrap. just wear the strap When it is hot in the summertime or in the south it is better to just wear the jockstrap by itself.
No, it is not. A jockstrap is a protective device for the genitals.
Boys can wear a jockstrap to hold a protective cup in place, which protects you from a direct hit in the genitals. Or, a boy can wear a jockstrap just for support, to keep everything from bouncing and moving while he runs or works out.
As long as you want to
This is completely up to you. If you wear boxers, normally you will put the jockstrap over the boxer or boxer brief. If you wear briefs you can wear it over or under. Anything smaller than that you might try wearing it under. Or you can just wear it as itself. It's a personal preference. I do not wear underwear with a jockstrap.
Yes. Yes he does.
