Between 20 and 25, I suppose. But thinking of Hugh Jackman or Keanu Reeves it is possible to say that some "boys" in their early forties look very nice!!
LOL you know it really depends on what end of the age spectrum you are judging FROM. When I was in my 20-30's, I thought the most handsome guys were in that age range. Now, as I get older, I find that while I can appreciate a good looking young guy - I think that an older man is much more attractive.
I'm sure this thread will keep on going - since people only read the title, and not the actual posts...
Boys are handsome from the day when they are born and till the day when they die Isnt it True Boys ?????
