Every true jock/cup fetishist feels a rush whenever he gets a new jockstrap or jock with cup and puts it on for the first time. I suppose it is similar to going to bed with somebody for the first time. Your genitals fill out a supporter. In most cases, it is a delightful experience.
Tonight I am wearing a Franklin MLB Baseball athletic supporter for the first time. This jock in men's large fits me perfectly, except the pouch is a little on the tight side. I thank my good buddy Don out in San Diego for hunting for these jocks at a Target store out his way.
