I agree. Men, just like women, all look for a connection. Only I am not sure if sex is a way to a lasting connection with men. It is more women who get emotionally connected to a man with whom they are sexually involved. Men on the other hand even appear to lose romantic interest in a woman right after they had sex with her. Women want to cuddle and linger; men are hungry, then fall asleep. They connect permanently to a woman for other reasons. Sex provides just an immediate physical gratification. This is due to the difference in reproductive functions of the respective genders and not a reflection of a character.
Of course , this is just one point of view, a theory, just a model for thought, something to play with , totally open to refutation . I am no expert, just flexing my thinking muscles.
