After one week of trying them, they are certainly not for men.  They fit well and feel good,but!  After just about 10 minutes of even mild walking one tends to fall out one side or the other.  While in non-stretch boxer shorts normal walking will cause positive re-adjustment, but since these are stretch they hold one in place requiring manly intervention  to reposition oneself correctly.  So unless you wish a lame excuse to reach down in public and do just that, don't buy these for a man.  I have a spouse that inherited them and she loves them.  She would give them 5 stars both for herself and the laugh she got out of seeing how I was positioned in them after just a short bit.
