The simple answer is: yes.
The complex scientifically-backed answer is:
Due to inherent differences in the genetic make-up and DNA-structure of gay men they are actually a sub-species of Homo sapiens: Homo sapiens homosexualus. Defining characteristics of Homo sapiens homosexualus are as follows:
1) Increased sex drive, while at the same time displaying decreased testosterone levels. While utterly perplexing in the general poplulation male Homo sapiens, it is universally found in the homosexualus subspecies.
2) Exceptionally large penises, although widely variable amongst "races" within the subspecies. The average white homosexualus penis is 8.47 inches in length and 6.83 inches in girth. The average black homosexualus penis is 10 inches length by 8 inches girth. The average asian homosexualus penis is 6 inches long by 4.5 inches girth. Other races match averages with the white population exactly.
3) A genetic predisposition to fanatic obsession over female pop divas. For reasons yet unknown to science, but clearly noted in all case studies, the shorter the pop diva in question, the greater the fanatical obsession.
4) A lisp. Homosexualus men have exceptionally well devoloped muscles in the tip of the tongue that hinder the oral formations requred to make the "s" sound.
5) Limp wrists. Studies show that nearly all homosexualus males lack normal ligature in the wrist. This explains the total absense of tendonitis and carpal-tunnel syndrom in a population that masturbates nearly as often as it copulates.
6) Obsession with body image. This characteristic is shown to be an exact correlation to the female non-homosexualus. Mitochodrial DNA evidence has actually proven that homosexualus is actually evolved from the female non-homosexualus. Indeed, every homosexualus male has female mitochodria.
7) Exeptionally small amounts of ejaculate, both on a per-incidence and over-all basis.
8) High tendancy toward sexual perversion. In fact, in the absence of other homosexualus mates, they have been known to attempt sexual contact with non-homosexualus males, children, animals, and inanimate objects. In fact, the only thing they won't fuck appears to be a non-homosexualus female.
Also noted in many, but not all homosexualus specimens: A nearly complete lack of body hair, high income potential, inability to perform in millitary settings, and STD investation.
