How can one have sex with a woman without being accused of rape?
If you have to ask a woman to sign a written contract before sex, then you're doing it wrong. Before engaging in sex (or any kind of sexually suggestive behavior) both parties must be absolutely sure of the willingness of the other person involved. It's called consent, and it can be crystal clear if you use common sense. Suppose a woman is on a date with you and she seems interested. Take your time. As the date progresses, any advances that you make should be incremental. With each move, if she continues to be enthusiastic, you can proceed with caution. But, if at any time she seems reluctant, unreceptive, recoils, backs away, seems unwilling or uses the all-important word "no", then you must immediately stop your advances. This is not rocket science. When two people are attracted to each other, and willing, the magic happens. If the magic is not there for either person, then hold off until the time is right, if ever. There is nothing so sexy as a woman whispering "make love to me" in your ear, but verbalizations (or written contracts) are not required. The point is, you should never force affection. When it's mutually consensual, with clear intentions, a gleam in her eye, a look of desire on her face, passion flows, leaving little doubt as to what's on your partners mind.
