Here is some advice:
- Girls. Lose weight. If your BMI is in the low 20s and you're in your 20s, you can just go sit at a bar and get hit on. You could make an online dating profile and get 10 guys every day. If you're still a virgin a month later and it's not by choice, you are one fucked up person and should seek mental help.
- Guys: Get a good job. The younger you are, the more having money matters and the older you are, the more NOT having money makes you a total piece of shit unattractive loser who no girl will find attractive ( strangely ). You can have almost any defect, if you have enough financial security you can find someone to bang. Money is the most important thing after the mid-20s. Before that, be tall and handsome. It's easy; just be born that way.
Failing all that, remember that you can lower your standards lol. Make an online profile, there's dozens of fat frustrated feminazis who get little attention from guys, so go court those. Warning: They are ugly, bitches and their career prospects usually lie in the Starbucks / Safeway range, but with a huge debt from their doctorate in East Asian studies with a minor in history.
At the end of the day, if you are a guy, you will most likely have to make the first move so if you're a shy antisocial nerd, go make an online dating profile and don't wait for girls to magically fall onto your lap. And lose some weight, for god's sake. Lol.
