This chart is absolutely ridiculous and actually pretty degrading to men. The majority of men fall into the "unsatisfying" range since very few men as as big as what is considered "satisfying". The average male penis size is 5-5.5 inches which means that more than half of the male population is apparently inadequate. I think this is a wrong stereotype to perpetuate. I absolutely disagree with this chart. Penis size does not matter. What makes a satisfying partner is one who is respectful, reciprocating, fun, and adventurous. Penis size does not matter at all. I literally have never come across a penis I haven't wanted to fuck and fellate. All penises are pretty damn great and there shouldn't be a stupid chart telling most men that they are not acceptable just because of something so trivial that has no bearing on how good of a lover they actually are.
