Generally, a jock has two leg straps that go no where's near the butt crease and a completely bare rear.

Usually a thong has a single strap in the rear that goes over or perhaps right into the butt crack, depending on exactly how long and wide the strap is and the size of the thong relative to the size of the thong wearer..

Also, Most jocks have wider (often one inch or more) elastic waist bands attached to a pouch with the pouch made of a textured rubber/cotton. I have seen a few jocks designed like this with a single rear strap like a thong, tho they are rare. Thongs can be found in any number of materials, all cotton, cotton/lycra, nylon/lycra etc.

The right (or perhaps wrong LOL) thong can put a lot of tension on the perineum area, which some guys are quite unaccustomed to, at least until they figure it out. There are a lot of nerve endings at the exact point where the thong strap attaches to the pouch of the thong, and the sensations can be, well, interesting to say the least. There is a little of that going on with the typical jock as well where the leg straps are attached to the pouch, but not to the degree it ordinarily happens with a thong.

Unless they are brain-dead most guys seem to get more than a little aroused when they put on a thong or jock strap for the first time. This has basically nothing to do with sexual orientation, but merely a natural body and mind reaction to the entire situation and having straps and elastic tugging at places where straps have never touched or tugged before.

Any guy who played a sport as a youth that required wearing a jock strap for the first time no doubt knows what I am talking about, not unlike a swimmer who puts on a Speedo for the first time. Most guys look back on this with mixed feelings involving a combination of wonder, amazement and apprehension. Something surely interesting is clearly happening but what it is could be really embarrassing as well. These mixed feelings are quite normal and a normal part of growing up.
