Xeronisus, which I hope none of you suffer from.
Hard to find an X word so I used Google.
Xeronisus is a little-used term for the inability to reach orgasm.
It’s likely that the term comes from the Greek word xeros, meaning dry or withered. However, as it’s not in common use today, its etymology is difficult to trace.
Today it’s more common to say someone with xeronisus has anorgasmia.
