I seen this a lot on PUA sites and on TRP. Basically if a girl doesn't do something for you, you ask yourself, if she was dating Ryan Gosling (or some other attractive male celebrity) would she do this for him?

Examples: wife doesn't want to change her last name, girlfriend doesn't want to swallow.

I think it's an interesting question for guys to think about when going about their relationship problems. I have seen with women that their behavior/sexuality often depends on what kind of guys they are with.
