just noticed this today as i was heading out for my run… usually in this weather, i wear tights (below 40) since it’s too cold to wear shorts. however, the prob w/ the tights is that they offer no “support” for the fellas. i know, i know, usually they just tuck right up after about 5 min or so, but i really dont like that initial floppage, and i dont like the ideas of having the boys being used as soccer balls by my knees when i’m 60! the only option i’ve come across is wearing a jock which seems to show an interesting “line” around my ass. what other options are there? (and no, the thought of a man thong for running, or even other “play” activities, is not an option! )
Duct tape.
These work good for me, or sometimes I just bust out a pair of tri shorts. Since I am male I don’t worry about “lines”

Why not just wear a pair of briefs underneath? That’s what I do when wearing tights.
There are plenty of running briefs out there which are good. Alot of them are made of sports type wicking materials now.
Just check out the web for something.
Then when it’s really cold get some Craft or Hansen type wind blockers to keep them warmer.
Why don’t you go “old school” and wear a jock? I do also wear some Champion coolmax briefs. They seem to work just as well, but cost 3 - 4x… JohnL
It gets hit by your “knees”?
Stay away from my G/F!
I wear Asics running underwear in the boxer-brief style. Really comfy and no jostling in the frank and beans division.
Try these:
Seriously!
Made out of coolmax, very comfortable, you can also wear them as every day underwear, and they don’t give you those panty lines you dread 
(Although strikingly similar, that’s not me in the picture, LOL!)
