Why girls naturally want more than sex and what to do about it

A man only needs sex to be happy. In contrast, a woman needs to have some guarantee that the man either has good genes or will take care of her in order to be happy. Nature has evolved our brains to interpret sex as the woman giving access to her reproductive ability. (These days she's not really doing that, but our brains are sill wired to consider it.) So, sex is always a good thing for the guy in his mind, always a chance to reproduce. It's not always good for a girl in her mind, unless it's with a person who either has good genes or is likely to provide. Most women use traits such as body form, body posture, body language, indications of confidence, humor, verbal and physical connections to others, or proficiency with some skill in order to determine if they guy has genetics that she wants. Body posture and indications of confidence, happiness, and connection to others seem to be some of the biggest attractors.

Considering all this, it's a mistake to think that having sex is just an enjoyable thing, equal for the man and the woman. For the man it's simply enjoyable. For the woman, her own mind will try to signal her that she's doing something wrong (or has done something wrong) if the man is either not likely a provider or doesn't have all characteristics that she wants. Considering that women often want an ideal, they probably have to deal with this built self criticism quite a bit. They're always on the search for a man with whom they can have sex and not feel regret. Because in nature, apparently the women who were careful about who they had sex with were more successful.

The practical consequence is that a man should continually convey confidence, happiness, and connection to others in order to continually attract a woman or women. And, he should continue to be a source of fun and a source of emotional support, so that she will continue to enjoy having sex without any doubts afterward. Although the physical pleasure of sex is always present, she doesn't want to deal with regret. And, the way to reduce the regret she predicts she will have is to convey and provide the aforementioned items, confidence, happiness, connection.
