I never considered that and that’s still uncomfortable af. But then again some people willingly wear corsets.

If someone does 15, they need to go to jail. A bra is uncomfortable to sleep with and sleeping with only a bra is psychotic.

We used other stuff before we had plastic and material science is still evolving. Latex glove and condoms still works. And stuff made from hard plastic could be made from metals, or some form of resin instead. Hell we didn’t stop using wood we learned to treat it to be more resistant.

Plus we have an issue of plastic everywhere. Maybe in the future it would be interesting to avoid using material that get everywhere and can’t be recycled.
