Probably got the idea from the manosphere. That being said, actually sticking to that particular habit is something to be proud of, and is completely harmless... when you are that low, anything you can be proud of is a win.

There is some evidence that taking cold showers is materially beneficial. If you don't have some underlying heart condition and can handle them, they're not bad, and they'll save on electricity/gas. The "nofap" thing is what concerns me, since that's a very "manosphere" concept with no middle ground between healthy sexuality and a crippling masturbation addiction (IIRC the former sometimes comes with crazy, unsubstantiated benefits in the fiction of the manosphere).

isn't cold water better for the skin? at least it feels like it, when i do it once ever few years

An ice plunge or rolling around in the snow both feel great afterwards. Really gets the endorphins going. The same applies to cold showers, although I usually do that only when I can get back into a 100°C sauna immediately after. That's double the endorphin rush.

You can do it too much. Had an ex fuck up his nerve endings with deathgrip bad enough he couldn't get off in me. Nobody's had trouble before or after so.

¯ \_(ツ)_/¯

but the solution is just do it less and grip less hard.

I also find that while we haven't got to needing to schedule sex yet, hubs and I do have to coordinate when we masturbate to get the best odds of mutual orgasm. His sweet spot seems to be 24-36h. Mine is technically as long as possible but if I try to wait more than a week I start having really surreal wet dreams about lizard people and people I haven't met in over a decade and it resets my refractory period to sometime next millennia.

Considering the rest of their lifestyle, there's very little chance that they were masturbating a sensible amount. A period of abstinence is a great way to normalize their masturbation habits.

Interviewer: So, you have an impressive resume…

Interviewee: OH NO… TRAIN IS LEAVING THE STATION

Speaking from experience

Twist: interviewer is Sharon Stone

I feel gross if I don't brush right after coffee. Can't imagine a month.

Itchy. Very itchy.

Every body is different, but generally for most people every 2-3 days tends to be the sweet spot for a full shower with shampoo, conditioner, etc.

Personally, I have greasy hair problems, and I ultimately found that showering less frequently made the biggest improvement of all of the changes I made. I'll generally shower every 2-3 days, and if I do something that makes me sweaty I'll hop in the shower and rinse off without using any product between those every other day showers

On the other hand, for OOP, they're making some big changes and probably need the consistency of every day to help maintain the habit they're building

some people are so depressed that they kill themselves, being stinky is small potatoes

Your body gets used to it.

Showering every day is also bad for your skin.
