THE FOLLOWING SITES CONTAIN SOME YAOI... THAT IS GUYxGUY STUFF. IF YOU ARE UNCOMFORTABLE WITH THIS, MY SUGGESTION IS NOT TO CLICK ANY OF THE LINKS BELOW

The difference between Shounen-Ai and Yaoi is that Shounen-Ai is more on an emotional level, while Yaoi is all about the physical part. These sites contain both yaoi and shounen-ai along with comedy, action, and fantasy mangas, but I just wanted to give a clear warning first!
