I have worn a type of suspensory by gosoftwear. I found the ability to separate the one from the other two to be very comfortable!

Men's thongs.

I always like the idea of boxers, but the reality is there's very little support for your balls and I find that the lack of it makes your balls hurt if you're wearing them for a long time. I will wear them around the house with a tshirt though. Definitely can't wear boxers when it's warm either, as I find they make my balls quite sweaty.

Prefer briefs or boxer-briefs for day-to-day work. Never tried a thong but have a few jockstraps occasionally for working out.

Comando or Jockstraps for me
 

I prefer comando or jocks myself

I prefer boxer briefs most of the time, but I wear bikini briefs a little bit as well.

I've always worn bikini briefs; although for the past year I've been wearing Equipo.

oh i thought it was what underwear you like on a woman...lol...well I prefer jockey shorts or as the label says all the way round "knockers"...it does get a laugh

I thought female panties would be ahead! It makes so much more sense, since when you don't have much up front, you don't need that big pouch! Plus how can a freshly shaved mini feel as good if it isn't wrapped in silky material. I remember along time ago, at the beach, my girlfriend and I were lying on towels and she couldn't resist touching my little bulge. Why? because I had a speedo style swim suit that outlined every curve. One man said while passing by:"If thats all I had , I wouldn't advertise!" Must have been jealous, not having a girlfriend who patted his penis in public!

I have to admit I'm not familiar with the different types of thongs so I don't know how a Brazilian one would differ.

If you barely feel them why wearing any? When I do have to wear clothes, going commando is the most comfortable, at least to me.

I wear briefs under boxers because I am too embarassed to let my ding a ling show
