Among some of the more well known advantages are:
no visible underwear lines, even under tight jeans/pants.
there is no possiblity that your underwear will ride up throughout the day.
it takes up much less space to pack thongs when you have to travel.
thongs provide for a tighter fit with less movement possible.
you will definitely get attention by wearing one, its still not a style that everyone wears – but you have to be ready for that attention!
Thongs aren’t just for women anymore. Most of the top mens underwear companies have a thong or two amongst their options. Like I said, do your research, find the ones that you like in color, fabric, style, etc. Go with a designer that understands the male form and remember with all underwear choices, if it doesn’t feel right on the rack – it won’t feel right on you!
