If you're not getting sex here's some sure fire, can't miss advise that will get you laid very regularly.
#1. Go crazy. Women can't resist wacked out crazy nutjobs. You should see all the women hanging off of Dixie!! Better, yet. Become a musician or a preacher and then go crazy. You'll have more women and sex then you'll know what to do with.
#2. Earn lots and lots of money. Women love men with money.
#3. Talk to a bunch of women and ask them what behavior they find irresistably sexy in a man, then do the exact opposite.
#4. Buy a big Harley. Women love riding on Harleys.
#5. Work out at the gym a lot. Women like fit men. If women tell you that they are not attracted to muscular men, see item #3.
#6. Watch soap operas. See the male characters? Never behave as they do. Their not men. Their women with testicles.
#6. Lie about your major at college (see item #1). Never tell them your a physics or engineering or accounting major. Tell them your majoring in Afican American Studies (But only if your white) or English Literature or Womens Studies.
#7. Women love and need drama. Give them what they need. Be a drama queen, even if your only acting (just don't let them know your acting).
#8. Never, ever act intelligent around women. If a woman your interested in is engaged in an intellectual conversaton discipline your self and refrain from contributing. Instead, do your best Al Bundy imitation. Stare off into space, look incredibly bored and put one hand down your pants (or pick ear wax out of your ear.). It will feed into the "weak mind, strong back" stereotype many women have about men.
#9. If the above fails as a last ditch effort pretend to be gay. Women love thinking the can convert or reform a gay man. This approach has been known to work but has a serious draw back. You may end up having sex but your partner might have a mustache.
If all this fails, don't even try a hooker. If your that big a loser they won't be interested in you either.
