Any sexual activity involving the anus and lower bowel ought be treated carefully as a health and safety hygiene risk.
Best safe practise should be prioritised and followed at all times...

Personally, it's not my cup of tea, but I'm well aware the extent to which American male heterosexuals
are obsessed with it.
Seemingly prizing it over vaginal sex...

Porn must obviously have played a part in normalizing this,
but I wonder to what extent the Catholic Church's age old ruling banning contraception
has played it's part over countless generations...???

It's a bit rich all these straight & christian men bumming their women,
then complaining how ungodly it is for gays to be doing exactly the same with each other... 🙄
