If you watch a video and you are not attracted to the person in it, keep it to yourself. The only kind of comments you should be making are constructive criticisms ("More lighting", "More volume", "Try to aim your cock towards the camera next time for the cumshot", etc.). There is already enough prejudice and bigotry in the world today without your childish, naive, picky ass making rude statements about somebody's body or face.
You need to remember that there are different types of people in the world and we are all attracted to different things. Some people like older men, some like heavy men, some like watersports, some like cross-dressing. If you don't, that's fine. Just don't make an ass out of yourself by announcing to everyone that a) you're not interested in seeing something you watched for free and b) you like to complain about things that have no effect on you.If you want to act like a 12 year-old, there are thousands of bulletin boards where you can do that. If you're old enough to have an account here, you should act like it.
