ABSTRACT
A man should control his ejaculation until a woman has an orgasm if the couple desires to achieve mutual orgasms during sexual intercourse. In male-oriented traditional societies, men have sexual relations without concerns about female sexuality. On the contrary, men's erectile dysfunction and premature ejaculation have been regarded as detrimental to sexual relationships since female sexuality has gained similar importance to male sexuality in the context of gender equality. Thus, many men would like to sustain erections for as long as desired and regulate their ejaculation like the experts in the Tantric sex or Taoism. Sexual techniques or teachings of the ancient Tantric sex or Taoism may sound illogical from a modern medical perspective, but they have something to teach us, such as focusing on foreplay to achieve female orgasm. Several issues on men's erectile capability and ejaculation are discussed in this article, while reviewing a variety of viewpoints on male sexual functioning.
