Are adults not supposed to have pubic hair anymore?

Of course ,don't be ridiculous. A the age of 25 every adult instantly sheds their hair. Its a sign of maturity. If you haven't experienced this you are probably a defect.

I trim not shave it off. Male here. I actually like pubic hair on women, but it's weird when they don't shave other areas

I don't understand the shaving nonsense. How did that idiotic trend get started? You should look like an adult, not a prepubescent kid.

It's a personal choice but my ex wanted all body hair gone so I lasered it off. No complaints from anyone for years now.

Sexual fads come and they go I'm not shaving unless I have a terrible case of crabs!

thats a personal choice................

Guess I'm not watching as closely as you are - but I do prefer them to have smooth balz, not hairy ones.....hate those hairs in my teeth.

It's not a fashion thing, it's a personal choice thing. Specially when it comes to grooming your body.

People have been shaving / trimming their pubic hair for decades, if not longer then that. Some people like having pubic hair some done. 

There is no "supposed to" when it comes to a person's individual grooming preferences.  If someone wants pubic hair then they can let it grow to its natural length.  If someone wants to trim it or shape it then they can do that, too.  If someone prefers it shaved smooth then they can do that.  Personally I prefer it shaved smooth on myself, and prefer that look on others, but there's certainly nothing wrong with it if someone else likes to have hair.    It's a matter of free personal choice.  The same goes for leg hair, armpit hair, head hair, etc.  Shaved pubic hair is just the current trend.  In a few decades everybody may very well be hairy again.

thats up to each person
