With classic tighty whities, boxers, boxer briefs, long johns, men’s thongs — even men’s lingerie — it seems like there are more types of men’s underwear now than ever before.

But how does a guy feel about it all (or does he just go commando and forget about it?) and which one, out of all those types, makes a guy feel the most comfortable in his own skin?

The survey was conducted on AskMen.com from Feb. 9–10, 2016. A total of 650 men were surveyed. The age breakdown was as follows: Under 18 (2 percent), between 18-24 (22 percent), between 25-34 (38 percent), between 35-44 (16 percent), between 45-64 (19 percent) and over 65 (3 percent).
