Why Guys?

I am sitting wondering why some guys think that if a woman takes her clothes off and shows her body that makes her a slut or a bitch or some other name that describes her in a bad light. But if a guy has a picture of his dick as an avatar, it is okay to do. To me that is a double standard from the past. I think personally that women that show their bodies are no worse or better than the next woman that does not show her body. Yes there are some women that are doing it to be called names like I wrote earlier, but I think they need someone to tell them that are better than that. They are needing to be shown respect and that they are some one in this world. As for the guys that have dicks for avatars, I just shake my head and think, what would your parents think of it? Would they be proud of your dick or think you were a pig and get you out of their basement to get a job. LOL
Seriously, women do not want to see a picture of your dick. They want to be respected and told everything nice. They don't want you posting on their profile thing like " you would look good sucking on my dick". Or "Bet you can't take it all". You need to talk nicely to them until you get to know what they want from you.
