I'm expecting my girlfriend to do certain naughty things with me that she did with past lovers even though she says she's outgrown them?
Are you really forcing your girlfriend to do something she doesn't want to do anymore?
We've had sex before, but she says she doesn't want to do those things anymore.
It sounds like your girlfriend's sexual preferences have changed. It's not okay to try to make her do things she doesn't want to, and she may leave you if you keep trying.
What if the girlfriend says she wants to.
If she wants to then that is when you can do those sexual acts with her. If she doesn't wanna have sex, then that is her right and forcing her to do so can be seen as sexual harassment and you may be put to jail with that. If you need more sexual experience with someone and your girlfriend can't deliver, I suggest you break up with her but tell her calmly and respectfully.
