people who are healthy and intelligent are full of jing or lifeforce. the easiest way to lose jing is through sex, but also the easiest way to cultivate it.
most men dont realise the power they have in their balls. if every sperm in a single ejaculation fertilized an egg, it could repopulate the UK twice.
Before humans had a higher intelligence, they were like animals.
sensuality and sexuality were not the same. people would only have sex during the mating season as was necessary, any other time they wouldnt ejaculate, but may be sensual with other members of the species, cultivating the jing so it was more powerful during the mating season. we have since evolved from that pure state and gained an intelligent mind. it would be wrong to deny any human sexual expression, because it is a fundamental aspect of our mind and body, but between those, it often gets confused. few men know how to please a woman because their energy gets depleted to quickly because it is volatile. these men should not have sex with women unless both them and the woman wanted children together. you can learn to retain your semen, and have multiple orgasms. this fills your body with jing and brings you to your highest potential. these are the people ,primarily, who should have children. homosexuality would be a good way to practise this.
ive read thats what dolphins, and monkeys, and even penguins often exhibit homosexual behaviour when overpopulated.
