You're not just a loser. You're a loser with a small dick. No woman wants to be with you, you are no one's "preferred size". If you actually get a woman, she will eventually cheat on you, and you can hardly blame her, can you. After all, being a loser is in your DNA and there is no reason she would stay. It's not just your "shortcomings" it's your whole genetic makeup as a loser that's fucked you.
