People say what we're all seeking is a meaning for life. I don't think that's what we're seeking. I think that what we are seeking is an experience of being alive, so that our life experiences on the purely physical plane will have resonance within our own innermost being and reality, so that we actually feel the rapture of being alive. Joseph Campbell The mission of A Theory and Celebration of Male Sexual Arousal by Females: The Foundation of Male Heterosexuality, is to glean insights into the origin and nature of the male rapture of being sexually alive. Males have a precious innate capacity and automatic disposition to joyously respond to the view and touch of beautiful nude females. Males actually do not have a choice. They must react with increasing levels of sexual excitement to increasing levels of perceived female beauty, as this genetic predisposition evolved from their ancient forefathers in order to facilitate reproductive success. Any male guilt about being sexually aroused by all gorgeous females should be abolished and substituted with an exultation of this wonderful gift from mother nature. Male sexual arousal by young, fertile females was probably the most important single evolutionary cause of reproductive success, and thus the ultimate determination of human survival. With insight into the origin and nature of male sexual arousal by females, males can consider their sexuality to be a self-actualization, a rejoicing, a rapture of being sexually alive.
