OP Singular,
I have felt your pain, and I cured it for myself. The answer is not to become someone you dislike or are uncomfortable with - but instead, to grow the person you are into a person you are MORE proud.
Besides this arbitrary idea of dating quantities and success score numbers judged by the numbers of responses, let's presume to say you would be happy finding just ONE person to start with who mutually is attractive and fun to be with. Let's not get overeager just yet looking for THE ONE for all eternity, if there even is such a thing (See Dan Savage videos). Let's take this process one step at a time - just get a date, any date. Ugly, fat, tall, short, pretty, sexy, smart, boring. Doesn't matter. Get a date. Then get two. Then three. Then more. And as you realize that people are people regardless of their exterior, you are going to become a far more likable, confidently social, comfortable, and engaging person - who SINCERELY unconditionally appreciates women - your charisma will naturally improve.
And women will sense that, because indeed you accept them absolutely regardless of what they would wish to do or say or act around you. You must learn and internalize that you are impervious to any of their negativity. To anyone's negativity, man or woman, because you utterly believe in yourself and the rich, successful, beautiful life journey that you are on. Your positivity is too strong, indeed. You don't beat yourself up, and think YOU are unlovable just because there IS SOMETHING WRONG WITH THEM. If you do these things, if you accept the things you can't change, your height, facial structure perhaps (plastic surgery?), whatever else you consider your lot in life, at the very least, you are going to become an extraordinarily popular personal energy to be around.
Now taking this self-embrace further, why not do things that will only better you? For instance, post a picture of yourself here, now that you have such a popular thread. Begin that effort you are no longer sensitive to the negativity anyone might bring to you commenting how you look, what height you are, or any other feature about you. 'Tis all just fodder to be examined, if there is or isn't something you can do to improve your situation. There ARE always things you can do, even if some things you have no control over. Proactivity, unconditional positivity, and pragmatism are your main principles now!
If you are indeed a bit scrawny and unhappy with your body structure, then learn to weight lift and grow your body. Take dancing classes, where your skills in dancing might overcome your physical structure. Do whatever else is active and physical, if you think that is the realm in which you lack.
I promise you, if you post a picture, or better yet, a video of yourself talking to us about your life situation, you are going to get immense and valuable feedback, far better than you are from the one dimensionality of textual defense and argumentation.. We don't, unfortunately or fortunately, live in merely a world of literal characters, so much as unique, unpredictable, infinitely dynamic human characters. =)
