I guess you aren't sending them the right vibes unlike other girls who make it well known that they not only like a guy... But they want then to be their man 😉😉😞😫so flirt harder next time you like a guy and see how that plays out http://oi63.tinypic.com/2vnnt5i.jpg
Finding a partner has nothing to do with how you look. You just haven't found anyone whom you have great chemistry or even there could be something you're doing, or something you believe that has kept you from getting involved in something serious.
Being in a relationship is awesome but I rather be single than being in a shitty relationship, far worse being with someone who will fuck you over.. I'd say don't wait for it, and keep your thing.
