All the good ones are taken. If the person isn't taken, there's a reason. The amount of love someone feels for you is inversely proportional to how much you love them. Money can't buy love, but it sure gets you a great bargaining position. If it seems too good to be true, it probably is.
Availability is a function of time.
The minute you get interested is the minute they find someone else. The more beautiful the woman is who loves you, the easier it is to leave her with no hard feelings. Nothing improves with age. No matter how many times you've had it, if it's offered take it, because it'll never be quite the same again. Sex has no calories.
