You might very well be a fine young gentleman. But the truth is, girls usually aren't strongly attracted to dudes that are smaller than they are. That just nature for you. In this post-modern era, women may indeed be more interested in things like sensivity, creativity, sense of humor, etc than the women in generations past when it comes to which men they find attractive. And, in theory, they are less impressed by muscles and machismo.
But in reality, most women still get a little weak in the knees when they see a dude built like the Incredible Hulk flex his muscles after he scores a touchdown. And, whether they admit it or not, they will fantasize about a guy like this carrying them to bed in his strong arms. A guy who will make her feel petite, yet safe.
In short, a girl doesn't want a scrawny little dude that makes her feel like a giant. Some girls think small guys are cute, but it's sorta the same thing as thinking a puppy is cute. You need to find a chick who is smaller than you. Get over it and go find her.
