How does gay promiscuity compare with that of lesbians?

Looking at sexual orientation, gender, and variety of sex partners is a good way to show how men and women really are very different. (The need to document this shows the crazy times we live in.)

According to evolutionary theory, since men can pass on their genes with minimal commitment, they have evolved the tendency to desire non-committal sex with a variety of partners.  Since having children is such a tremendous investment for women, they have been selected to be much choosier about sexual partners.  It's not typically hard for a women to get sex, but it can be a challenge to find partners who have the willingness and ability to provide resources to the offspring, or at least who have high-quality genes to pass on to one's children. 

If you're paying attention, you can see that a conflict arises: men who want many partners, and women who want few.  So many men are not able to get what they want.  But what about gay men?  There is no sexual conflict for them: just a bunch of guys who want novelty.

The General Social Survey (GSS) asked adults about: 1) sexual orientation, and 2) the number of male and female sex partners since age 18 (sample size = 23,579). Let's look at the numbers for male partners first:

















Gay men average 43 male partners--much more than any other group. Coming in at a distant second is male bisexuals with close to 15 men.  Female bisexuals have a mean of roughly 12 male partners, and straight women report an average of 5.5.  The average for lesbians is a little over two men.

Now for the number of female sex partners since 18: 

















The category with the most women partners is bisexual men with a mean of almost 20.  Next is straight men with almost 16 1/2.  Lesbians average close to eight female partners, and the mean for female bisexuals is around 5.  The mean for gay men is 2.6 women.

If we add together partners of either gender, the ranking for the total number of sex partners since 18 looks like this: #1) gay men, #2) bisexual men, #3) bisexual women, #4) straight men, #5) lesbians and #6) straight women.

So, sexual minorities have the most partners, but gay men and lesbians stick out; gay men because their numbers are so much higher, and lesbians because their numbers are atypically low.  Compared to lesbians, gays have around 4 1/2 times the number of partners.

This is consistent with evolutionary theory: men like sexual variety much more than women, and they show this most clearly when they are pursuing partners who also like variety; namely, other men.  Lesbians are not like other sexual minorities in that they do not pursue variety much. Why? Because they are women dealing with female partners.
