Well it is one of my favorite subjects. So no sweat off of my back. ;p

well you don't have to look but for some including me it makes it better, however back on point. It's nice, warm and comfortable. Like  the best glove in the world on the coldest place imaginable. LOL 

Masturbation has nothing on the real thing. All girls are formed different, so some better some worse. Some girls have some good, Yea I will leave it at that. You are most likely young and this sort of thing will completely change. In the future you will want to see as many as you can.

no but if you do not lube it up and it's dry it can cause friction. However most girls, teen girls/early 20 yr old girls get really wet during arousal. Really girls are the only ones who feel the pain at first but it's usaully when there virginity has been taken. However it is the best feeling in the world. Why do you think people do so many stupid things for it. People will end life long friendships for it, pay for it, kill for it and die for it. Now thats powerful.

If you masturbated and you will if you have not, everyone does, Don't let them lie to you. When you get older people all admit it, when your younger it's always being denied. It's ten times better then self pleasuring. Do not be ashamed of your sexual life. This is a major flaw with many. There is nothing wrong with it and actually orgasims add years to your life.
