I am not sure about the heated seats (would be nice in the case when I am in one of my great virus fevers, admittedly, but probably can’t justify those few occasions for that cost), but the bidet and dryer are the bomb.
As one who lacks a gall bladder, I spend more time than I would like with the porcelain throne. And after a while, toilet tissue feels like sand paper. I have a very simple bidet (look up Tushi Clean, I found it by searching for other gall bladder-free sufferers). That thing is a blessing from The Lord. Reduces toilet paper use too. Could make that zero if the thing had a blow dryer. My next house will have the dryer and the bidet.
So judging men’s sexuality on their use of a bidet, is just nuts, IMO. Plus the fact, that after using a bidet, you realize just how nasty you remain with toilet tissue. Flushable wet wipe sales are not increasing without reason... and unfortunately clogging many sewer systems in cities (and rural areas too, their tank systems).
But on the other side, buying one of these multi-kilodollar contraptions could be considered nuts as well (unless you just have money to toss overboard).
I was being a bit tongue in cheek.
For post-gall bladder problems such as you describe, probiotics such as Activia, 1 to 3x daily, are helpful. The Aldi food store chain also has a store brand. There are higher-tech probiotics in capsule form on the health-food market as well.
