A paramour is an “other lover”. Para = beside, amour = love. It’s not a casual fuck buddy, it’s your cheating partner. I’m surprised to hear you say it’s unknown as a word these days? Seems like just a normal word to me, albeit one I’m happy to go without using as cheaters suck.
I will say that the blow dry option doesn’t really help sufficiently after using the bidet to avoid me wanting to use TP to dry off, but it might be sufficient for lady parts after peeing. Don’t have a vagina personally, so can’t say for sure.
