I think it’s all just preference really. Sometimes people like certain things, but it doesn’t mean who they end up with absolutely has to have it. For instance I have a thing for Asian men, but that doesn’t mean I won’t date a guy who isn’t Asian.
Although the other week I was listening to the Savage Love Podcast and a woman called in about her thing for outty belly buttons, and how she loved a guy who had an inny and it really bothered her. Dan Savage simply said, if the person doesn’t have the trait that you absolutely need them to have to be romantically attracted to them, then you are allowed to break up with them.
Now I feel like I am rambling. What I mean is, I don’t know of any double standard out there, I guess most of the time it’s either a big deal or not to them. To each their own.
