Two animals coming together for the purposes of sexual reproduction is called mating. Most animals only mate when the female is at the point of estrus, which is the most fertile period of time in its reproductive cycle. In certain animals, sexual intercourse is not only used for reproduction, but has taken other functions as well. These animals include bonobos, dolphins, and chimpanzees which also have sexual intercourse even when the female is not in estrus, and to engage in sex acts with same-sex partners. In most instances, humans have sex primarily for pleasure. This behavior in the above mentioned animals is also presumed to be for pleasure, which in turn strengthens social bonds.
The sexual response cycle is a model that describes the physiological responses that occur during sexual activity. This model was created by William Masters and Virginia Johnson. According to Masters and Johnson, the human sexual response cycle consists of four phases; excitement, plateau, orgasm, and resolution, also called the EPOR model. During the excitement phase of the EPOR model, one attains the intrinsic motivation to have sex. The plateau phase is the precursor to orgasm, which may be mostly biological for men and mostly psychological for women. Orgasm is the release of tension, and the resolution period is the unaroused state before the cycle begins again.[page needed]

Missionary is one of the most popular sex positions because it delivers results. It is intimate, allowing you to gaze deep into your lover’s eyes as you reach the finish line. “The positioning and motion stimulates the woman’s clitoris, which is what the majority of ladies (close to 70 percent) need in order to orgasm,” says sexologist and Sex With Emily podcast host Emily Morse. “Perhaps this is why women have been rating it their top pick over the years.”
Males and females are anatomically similar; this extends to some degree to the development of the reproductive system. As adults, they have different reproductive mechanisms that enable them to perform sexual acts and to reproduce. Men and women react to sexual stimuli in a similar fashion with minor differences. Women have a monthly reproductive cycle, whereas the male sperm production cycle is more continuous.[page needed]
People use a few common labels to identify their sexuality. Your sexuality isn’t defined by who you have sex with – it’s about how you feel and how you choose to identify yourself. The important thing is that you choose what label feels comfortable, or you choose no label at all. You might find, like many others have, that the label you choose changes over time.
