everyone has different interests. I don't really go for women I find to be 'hot'. I prefer more reserved women that don't flaunt themselves.
Chemistry has a lot to do with it, but I am really turned on by a gal who has no problems talking about whatever. Not being ashamed of being who they are. And sure, you have to be attracted to them.
If she's burps loudly after she swallows my load, she's hot.If she wants to hump back when my dog humps her leg, she's not.
I put hot girls below the rest because generally (generally!) they spend lots of time and money changing how they naturally look so that other people will be attracted to them.
