To borrow a phrase from a current pop culture figure, you might consider that your “picker” is broken. In other words, perhaps you are finding yourself attracted to the wrong type of girl. I agree with you that it seems our society is becoming more narcissistic and superficial in some ways (this is the age of the “selfie”). However, for every flawed girl who only knows how to express affection through sex, there are loads others who would share your more romantic (and in my view, healthy) notion of relationships and dating. What do you find attractive in a girl? The fact that this seems to be a pattern in the type of women you pursue might be a good reason to look inward and really ask yourself “why am I attracted to her?” You describe the girls as “vapid and capricious”, so what are you interested in about them? You don’t have to feel “used” for it to be a bad idea to become more physically involved than you would like at any given time. Sure, they might want relationships just as you do, but you don’t want a relationship just for the sake of having one with just anyone I’m sure. It’s ok to say “next!” when you realize your relationship needs are incompatible.
