If you wear one correctly it feels really erotic because the jock hugs your genitals.The old ones did that better than the all polyester ones that became common in the 1980,s.They were course feeling and not very comfortable.
Futuro made great jocks back in the 1970,s because they used cotton,rayon,and rubber in their construction. They seldom show up really because repeated washing would destroy them but they were really comfortable to wear
Don,t forget Defender but Futuro really made i think the most comfortable jockstrap in the 1970,s. Rubber,rayon,cotton mix. They aren,t around. Very rare.I like Bike into the 1980,s then the pouches got really uncomfortable
