Wish I could give a clinic in this stuff. Better than a membership with a fraud site. Accept that forking out for that first date with no sex will likely be the price of getting regular sex down the road.
The hints will screen out the prudes, while the nicely written profile will get you a higher caliber woman. When texting with the woman, hint at your sex drive without overwhelming them with it. Have many good photos and write an interesting, grammatically correct profile. List your intentions as long-term relationship, no matter how inaccurate that is.
Your best - no, your only option - is to use legitimate dating sites. This comes from a guy who has lost count of how many women I've pounded from online dating, so listen up.
