Is it normal to selfsuck and to want to show my girlfriend

maybe suggest watching a porno with a guy that does that, and watch her reaction. If she thinks it's cool just suggest "oh hey I was pretty flexible when I was younger, I wonder if I could do it?" and if she seems into it then show her. Maybe don't mention that you've been sucking yourself off since you were 16 though

Do some exploring b4 you tell her about it, see how she'll react. I once told a g/f that I could shoot into my mouth lying done, and she was dying to watch. I did it for her when she was on her period, and she went nuts.

I showed my girl friend. She loved it. Occasionally she asks me to do it and masturbates while I do. A lot of guys can do this, more than want to admit. Its an amazing feeling.

1- don't tell us how big your dick is, 'cause u sound like a lying tiny bitch, even if you aren't.
2- that's kinda pathetic, even by my standards.
3- you must be crazy flexible, or just really determined, the latter being kinda sad.
4- as a straight man, i get the feeling that a girl (unless she frequently felatios) wouldn't really be wanting to kiss a guy that does that.

I reserve that for girls and jizzcore

WOW I didn't think that was possible without removing your ribs! Kudos to you!
I agree with DADNSCAL - definitely see what she thinks about that kind of thing before you show her. It might turn her off, though it might like it (I know I would)!
