Shit makes my blood boil. I thought this was all about "love"? Remember: love is love.

Any complex system with a high number of interactions is going to select for properties that are most easily magnified by those interactions. In other words, you can use PrEP as a barrier to HIV infection, vaccinate away the MPX, but if you're participating in a culture where 20+ hookups a month are the norm, then you're going to encounter some other unpleasant or even lethal pathogen. That's what pathogens do, they find the best way to propagate themselves. Gay orgies represent excellent opportunities for microbes.

Imma quote the Bible, not because I believe it is the literal word of God, but rather because it provides an interesting historical perspective. Romans 1:27: In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error. In other words, this shit was happening 2000 years ago, with the same natural laws governing the behavior of complex systems, and people still have not learned to keep their dick in their pants.
