Many others cannot separate sex from all other aspects of their relationship. Each begins to affect the other. Keep in mind that resentments, tensions, feelings of being used by the other, and fears about the relationship can arise. Emotional involvement can lead to anxiety about what a relationship means, where each stands in the other's eyes, and what plans are in the future. It is hard, and unacceptable for most, to carry on a long-term sexual relationship without emotional involvement.
Many people can and do have sex without love, but many also prefer sex with love.
Female, Junior Dr. Caron's Answer Promiscuity is a label that some people use to describe the behavior of those who have sex with a variety of different partners on a casual basis. Because of the double standard, it's more often used in a negative way to describe women. Clearly there are some people who enjoy sex with a variety of partners, and prefer to avoid getting emotionally involved. According to Gina Ogden, author of Women Who Love Sex, if a person engages in this kind of behavior in a responsible, nonexploitative manner, taking appropriate steps to reduce risks of disease and pregnancy, and emerges from them without negative feelings or conflict, there is no particular reason to judge the behavior as a problem. Sometimes, however, having multiple sex partners may be motivated by something else.
