The research I've read that goes at least into the early 2000's suggests that there is a decent sized statistical jump between gay men and the rest of the population in lifetime sexual partner rate. Straight men and gay women are roughly comparable, and straight women are on the low end.
There are lots of different numbers out there, so it really depends on how a study is designed, what birth cohorts it includes, and what region it focuses on.
Some of the earliest studies were done in the 1970s among populations of self-selecting, urban gay males. These often concluded that gays were extremely promiscuous, averaging over 250 lifetime partners. Well, obviously if you're recruiting your respondents from gay bars and gay baths then you're going to get a fairly promiscuous sample.
Studies with better methodologies show more parity between gays and straights. For example, Leridon, van Zessen, and Hubert find that in some countries in Europe gays actually have
fewer median lifetime sexual partners, though Norway is the only one where the mean is lower. The authors note that the mean in Great Britain is skewed upward by a small group of highly promiscuous persons with many partners. (Compare
this chart for straights to
this one for gays.)
The National Health and Social Life Survey in 1994 was the first representative national survey to collect data for the US. It found that the mean number of lifetime sexual partners was 16.9 for heterosexuals and 26.6 for homosexuals. Again, these are means, not medians, so they may be skewed by a small, highly promiscuous group.
One of the most remarkable charts I've seen recently is the data published by the dating website OKCupid showing that the distributions of lifetime partners for gays and straights registered with their website are roughly the same. (Admittedly this is a self-selecting group, but all the other studies have sample limitations of their own, so I don't think we should dismiss this out of hand.) The site owners observe, "It turns out that a tiny fraction of gays have single-handedly created the public image of gay sexual recklessness—in fact we found that just 2% of gay people have had 23% of the total reported gay sex, which is pretty crazy." This would tend to confirm the Leridon, et al observation that mean partner numbers for gays are skewed upward by a small group of highly promiscuous people.
