My GF will not let me do her in the ass and need help advice getting her to let me do this I have never done the ass so I definately need to try this what will work???

Sounds to me you're trying to force something.
You can pick your nose, you can pick your friends but you can't pick your friend's nose..[er butt in this case]

Give it time. I'm sure when you sit back and enjoy the ride and not so much push upon her, she'll come around..
Wow..I didn't mean to but many puns here.

Just give it up bro, it's not worth it anyway. It is painful for both, imagine if she tried sticking something that size in yours. You will hurt too, it is like trying to push a quarter through a dime slot.
