Sexual relationships between members of the same sex expose gays, lesbians and bisexuals to extreme risks of Sexually Transmitted Diseases (STDs), physical injuries, mental disorders and even a shortened life span. There are five major distinctions between gay and heterosexual relationships, with specific medical consequences. They are:
- Levels of Promiscuity
Prior to the AIDS epidemic, a 1978 study found that 75 percent of white, gay males claimed to have had more than 100 lifetime male sex partners: 15 percent claimed 100-249 sex partners; 17 percent claimed 250-499; 15 percent claimed 500- 999; and 28 percent claimed more than 1,000 lifetime male sex partners. Levels of promiscuity subsequently declined, but some observers are concerned that promiscuity is again approaching the levels of the 1970s. The medical consequence of this promiscuity is that gays have a greatly increased likelihood of contracting HIV/AIDS, syphilis and other STDs.
Similar extremes of promiscuity have not been documented among lesbians. However, an Australian study found that 93 percent of lesbians reported having had sex with men, and lesbians were 4.5 times more likely than heterosexual women to have had more than 50 lifetime male sex partners. Any degree of sexual promiscuity carries the risk of contracting STDs.
- Physical HealthCommon sexual practices among gay men lead to numerous STDs and physical injuries, some of which are virtually unknown in the heterosexual population. Lesbians are also at higher risk for STDs. In addition to diseases that may be transmitted during lesbian sex, a study at an Australian STD clinic found that lesbians were three to four times more likely than heterosexual women to have sex with men who were high-risk for HIV.
- Mental HealthIt is well established that there are high rates of psychiatric illnesses, including depression, drug abuse, and suicide attempts, among gays and lesbians. This is true even in the Netherlands, where gay, lesbian and bisexual (GLB) relationships are far more socially acceptable than in the U.S. Depression and drug abuse are strongly associated with risky sexual practices that lead to serious medical problems.
- Life SpanThe only epidemiological study to date on the life span of gay men concluded that gay and bisexual men lose up to 20 years of life expectancy.
- MonogamyMonogamy, meaning long-term sexual fidelity, is rare in GLB relationships, particularly among gay men. One study reported that 66 percent of gay couples reported sex outside the relationship within the first year, and nearly 90 percent if the relationship lasted five years.
Encouraging people to engage in risky sexual behavior undermines good health and can result in a shortened life span. Yet that is exactly what employers and governmental entities are doing when they grant GLB couples benefits or status that make GLB relationships appear more socially acceptable.
