Women who have sex with women
Encyclopedia
Women who have sex with women (WSW) is a term used to identify women who engage in sexual activities with other women, whether or not they identify themselves as lesbian
Lesbian
Lesbian is a term most widely used in the English language to describe sexual and romantic desire between females. The word may be used as a noun, to refer to women who identify themselves or who are characterized by others as having the primary attribute of female homosexuality, or as an...

 or bisexual. The term is often used in medical literature to describe such women as a group for clinical study, without needing to consider the issues of sexual self-identity.

Physical

In terms of medical issues, the sexual identification of women who consult a medical professional is usually not sought nor volunteered, due to the misconceptions and assumptions about lesbian sexuality and the hesitancy of some women in disclosing their accurate sexual histories even to a physician. Many women who do not participate in heterosexual activity do not go to see a physician because they do not require birth control

 or types of cancer. A factor which leads to lesbians neglecting to seek medical screening in the United States is a lack of health insurance offered by employers for same-sex domestic partners.

When women do seek medical attention, medical professionals often fail to take a complete medical history. In a recent study of 2,345 lesbian and bisexual women, only 9.3% had claimed they had ever been asked their sexual orientation by a physician. A third of the respondents believed disclosing their sexual history would result in a negative reaction, and 30% had received a negative reaction from a medical professional after identifying themselves as lesbian or bisexual.

A patient's complete history helps medical professionals identify higher risk areas and corrects assumptions about the personal histories of women. In a similar survey of 6,935 lesbians, 77% had had sexual contact with one or more male partners, and 6% had that contact within the previous year.Another summary of overall surveys found that women who identify as lesbian, 80-95% had previous sexual contact with men, and some report sexual behavior that is risky.(King, p. 221.)

, both of which are more prevalent in lesbians. Studies show that lesbians have a higher body mass and are generally less concerned about weight issues than heterosexual women, although they are more likely to exercise regularly.

Lack of differentiation between lesbians and heterosexual women in medical studies that concentrate on health issues for women skews results for lesbians and non-lesbian women. Reports are inconclusive about occurrence of breast cancer

 rates are higher in lesbians than in heterosexual women, perhaps because many lesbians lack protective factors of pregnancy, abortion, contraceptives, breast feeding, and miscarriages.

Mental

Since medical literature began to describe homosexuality, it has often been approached from a view that sought to find an inherent psychopathology as the root cause. Much literature on mental health and lesbians centered on their depression

. Although these issues exist among lesbians, discussion about their causes shifted after homosexuality was removed from the Diagnostic and Statistical Manual in 1973. Instead, social ostracism, legal discrimination, internalization of negative stereotypes, and limited support structures indicate factors homosexuals face in Western societies that often adversely affect their mental health. Women who identify as lesbian report feeling significantly different and isolated during adolescence; these emotions have been cited as appearing on average at 15 years old in lesbians and 18 years old in women who identify as bisexual. On the whole, women tend to work through developing a self-concept internally, or with other women with whom they are intimate. Females (heterosexual or otherwise) also limit who they divulge their sexual identities to and more often see being lesbian as a choice, as opposed to gay men, who work more externally and see being gay as outside their control.

 are the most common mental health issues for women. Depression is reported among lesbians at a rate similar to heterosexual women. It is a more significant problem among women who feel they must hide their sexual orientation from friends and family, experience compounded ethnic or religious discrimination, or experience relationship difficulties with no support system. More than half the respondents to a 1994 survey of health issues in lesbians reported they had suicidal thoughts

, and 18% had attempted suicide.

A population-based study completed by the National Alcohol Research Center found that women who identify as lesbian or bisexual are less likely to abstain from alcohol. Lesbians and bisexual women have a higher likelihood of reporting problems with alcohol, as well as not being satisfied with treatment for substance abuse programs. Many lesbian communities are centered in bars, and drinking is an activity that correlates to community participation for lesbians and bisexual women.

 (BV) occurs more often in lesbians, but it is unclear if BV is transmitted by sexual contact; it occurs in celibate as well as sexually active women. BV often occurs in both partners in a lesbian relationship; a recent study of women with BV found that 81% had partners with BV. Lesbians are not included in a category of frequency of Human Immunodeficiency Virus (HIV) transmission, although transmission is possible through vaginal and cervical secretions. The highest rate of transmission of HIV to lesbians is among women who participate in intravenous drug use or have sexual intercourse with bisexual men.
