A large survey conducted through gay dating sites and Facebook in Australia has found that previous surveys may have overestimated the proportion of gay men who are in emotionally committed relationships, and in monogamous ones. Three-quarters had ever tested for HIV and half in the last year. Seventy per cent described themselves as having a regular partner. Studies aim to give information that will be applicable to a large group of people e. Because it is impractical to conduct a study with such a large group, only a sub-group a sample takes part in a study. Many people find this term stigmatising as it suggests information which is normally kept secret.
an unequal distribution of partners: gays versus straights
How many people have Americans had sex with? | Relationships in America
Do some gay men have lots of partners while others have very few? Is the inequality in partnerships among gay men greater than how unequally women partners are distributed among heterosexual men? What about straight women versus lesbians? In our last post , focused on heterosexuals, we showed that women partners are more unequally distributed among men than male partners are among women, and that partners are more unequally distributed among singles than those who are in a marital or cohabiting union. Here, using methods similar to those in our previous post, we use Gini indices to compare gay men, straight men, lesbians, and straight women in how unequally their sexual partnerships are distributed. The technical details of what we did are explained at the end of this post.
Americans vary widely in the number of sexual partners they report over a lifetime. Few never have sex, while a non-trivial number report sex with only one person: those who have had only one sexual partner comprise 16 percent of adults ages On the opposite end of the spectrum, very few people report high numbers of lifetime sexual partners: just two 2 percent of heterosexual 37 women and three 3 percent of heterosexual men report having had more than 50 opposite-sex sexual partners, while two 2 percent of self-identified lesbian women 38 have had over 50 female partners. Thus, the experience of large numbers of sexual partners is uncommon for the vast majority of the population. The exception to this is self-identified gay men.
A study analysing transmission patterns between gay men in a cohort of patients in San Diego, California has found the strongest scientific evidence so far that concurrency — having ongoing sexual relationships with more than one partner at the same time — is an independent predictor of HIV transmission. However these two observations did not reach statistical significance. By comparing the genetic sequence of the virus in different individuals, scientists can identify viruses that are closely related. A transmission cluster is a group of people who have similar strains of the virus, which suggests but does not prove HIV transmission between those individuals. Studies aim to give information that will be applicable to a large group of people e.
