Behavior patterns are generally unwritten and constantly changing.
There are considerable differences between social and personal values.
Each culture has particular patterns which determine such choices as whether the man asks the woman out, where people might meet, whether kissing is acceptable on a first date, the substance of conversation, who should pay for meals or entertainment, Since dating can be a stressful situation, there is the possibility of humor to try to reduce tensions.
For example, director Blake Edwards wanted to date singing star Julie Andrews, and he joked in parties about her persona by saying that her "endlessly cheerful governess" image from movies such as Mary Poppins and The Sound of Music gave her the image of possibly having "lilacs for pubic hair"; While the term dating has many meanings, the most common refers to a trial period in which two people explore whether to take the relationship further towards a more permanent relationship; in this sense, dating refers to the time when people are physically together in public as opposed to the earlier time period in which people are arranging the date, perhaps by corresponding by email or text or phone.
While the term has several meanings, the most frequent usage refers to two people exploring whether they are romantically or sexually compatible by participating in dates with the other.
However, one particularity of the human species is that pair bonds are often formed without necessarily having the intention of reproduction.
In modern times, emphasis on the institution of marriage, generally described as a male-female bond, has obscured pair bonds formed by same-sex and transsexual couples, and that many heterosexual couples also bond for life without offspring, or that often pairs that do have offspring separate.
As humans societies have evolved from hunter-gatherers into civilized societies, there have been substantial changes in relations between men and women, with perhaps one of a few remaining biological constants being that both adult women and men must have sexual intercourse for human procreation to happen.
Humans have been compared to other species in terms of sexual behavior.
