In your opinion you may consider them significant. In my opinion I wouldn't.

I can think of several ways that the two are alike. Neither can or will ever produce offspring and are not taken part in with the intent of producing offspring, neither are accepted by most cultures or religions and both facilitate the spread of disease.

And neither are natural.

Unfortunately there are heterosexual unions that neither can nor will promote offspring either. There are those who by surgery or by nature who are no longer able to produce offspring. So this distinction falls short.

Sexual intercourse spreads disease. I'm sure you realize that diseases have been, are being, and will be spread by heterosexual intercourse.
