The biological and physical aspects of sexuality largely concern the human reproductive functions, including the human sexual response cycle. [3][4] Someone's sexual orientation is their pattern of sexual interest in the opposite and/or same sex. [5]

Zoophilia is a paraphilia in which a person experiences a sexual fixation on non-human animals. [1][2][3] Bestiality instead refers to cross-species sexual activity between humans and non-human animals.

In turn, sexual selection leads to the evolution of sexual dimorphism in mate choice, competitive ability, and courtship displays (see secondary sex characteristics).

In humans and other mammals, this male organ is known as the penis, which enters the female reproductive tract (called the vagina) to achieve insemination —a process called sexual intercourse.
An erection is the stiffening expansion and orthogonal reorientation of the penis, which occurs during sexual arousal. Erections can occur in non- sexual situations; spontaneous non-sexual erections frequently occur during adolescence and sleep. In its flaccid state, the penis is smaller, gives to pressure, and the glans is covered by the foreskin.

Here's some information and tips to help parents tell the difference between "normal" sexual behaviors and behaviors that may signal a problem.
Humans Human female and male In humans, sex is normally either male or female. For example: John's sex is male. Jane's sex is female.

A man's sperm contains either an X or a Y ...
