More than a quarter of men feel the same way. Eric Rechsteiner Ai Aoyama is a sex and relationship counsellor who works out of her narrow three-storey home on a Tokyo back street.

Back then, about 15 years ago, she was Queen Ai, or Queen Love, and she did "all the usual things" like tying people up and dripping hot wax on their nipples.

Overview The male gamete sperm fertilizing the female gamete ovum One of the basic properties of life is reproduction, the capacity to generate new individuals, and sex is an aspect of this process. Life has evolved from simple stages to more complex ones, and so have the reproduction mechanisms. Initially the reproduction was a replicating process that consists in producing new individuals that contain the same genetic information as the original or parent individual. This mode of reproduction is called asexual, and it is still used by many species, particularly unicellular, but it is also very common in multicellular organisms, including many of those with sexual reproduction.

Coitus is derived from the Latin word coitio or coire, meaning "a coming together or joining together" or "to go together", and is known under different ancient Latin names for a variety of sexual activities, but usually denotes penile—vaginal penetration. Lerner and Laurence Steinberg state that researchers also "rarely disclose" how they conceptualize sex "or even whether they resolved potential discrepancies" in conceptualizations of sex. While most consider penile—vaginal intercourse to be sex, whether or not anal or oral intercourse is considered sex is more debatable, with oral sex ranking lowest. Human mating strategies and Pair bond Copulation ranges from a purely reproductive activity to one of emotional bonding. For example, sexual intercourse and sexual activity in general often play a strong role in human bonding.
