Psychological doesn't mean "you can't become a functional human without it". it means "without it, the mental state of a significant amount of humans will be altered". Under that definition, there is certainly an argument to be made about sex in some forms being a "psychological need". which build off the 3 universal psychological needs of autonomy, competence, and relatedness:

There are many much more well studied people who have spent much longer debating this, so I'm not interested in debating this here. I just want to note that valid arguments exist, and that I feel you are still conflating "basic" with "psychological".

If you'd like another more controversial example: consider parental supervision. You can live a healthly life without ever leaving your parents' home nor ruleset. And in some other societies it is entirely expected to live in your parents' home even after marriage alongside one's parents (still following their personal values). However, some may argue that this hampers the psychological needs of autonomy and competence. That one will never have true control and choice and that you can never truly go out and challenge oneself while under a parent's wing.

Much like the basic "needs" of sex, this can be under contention and is ultimately up to society. A few anecdotes of those who made it or not doesn't rule it out as arguably being a psychological need not being met. Much like a few asexual people not necessarily ruling out sex as aruably being a psychological need at some leve.

Let's not get too far away from my original point. When people say "sex is a basic physical need", they want to imply or paint the association that it's like water and air. It's not like that.

"People" say a lot of things that may or may not be outdated, outright stupid, or otherwise missing nuance. If that's your original point, I'm not interested in it, to be frank.

I'm mostly responding to the original idea of "Putting it on that pyramid has somehow fallen out of favor". your initial response of "It's not a basic physical need. It's a psychological need. " made it sound like it didn't deserve to be on bottom part of the pyramid, or that you perhaps didn't know that those two categories are often the same part of the pyramid. So I responded in turn to inform.
