Women and men are wired differently, I get it. While men are highly stimulated by visual things, women prefer emotions and words. So, I understand, kind of, why guys like it when girls text them pictures. And, why guys constantly ask girls to send them pictures of themselves, especially when they're just getting to know each other.
However, guys, take note: chicks do not, DO NOT, want you to send them a picture of your crank (or member, or Johnson, or however else you refer to it).
Guys like getting pictures of boobs, of course. Because guys are visual creatures and because boobs are generally nice to look at. But, I hate to break it to you guys, your member is not attractive.
