Been wearing briefs for almost 7 years now, after wearing boxer shorts most of my life. I was talked into giving them a try by a couple of friends of mine who had made the switch themselves. I tried them out and have not looked back.
I tried boxer briefs a couple of times before switching to regular briefs but I did not like the feel of the snug material on my legs. Also, now that I wear briefs, the support of boxer briefs does not compare to that of briefs.
