If there are not already people running fediverse nodes that exist specifically to harvest potentially 'interesting' data, there will be.
You edited it? That's maybe interesting. You deleted it? Same deal, maybe interesting.
It looks like an email address? Definitely might be interesting. A phone number? Yep.
An address? Definitely could be interesting.
If you posted it, assume that it will always be available to the exact people that you don't want to see it.
When I was a teenager, well, there's a whole lot involved, but I basically didn't have any dental hygiene to speak of.
Who cared?
Well, I had more than one root canal by the time I was 20.
I'm a bit obsessive about it these days, but I have not needed any more root canals.
Take care of the teeth that you want to keep. Don't worry, if you don't, they'll go away.
The other big problem is that if it's big enough, it may be uncomfortable or down right painful for any partner.
Again, that's usually more of a girth than a length problem, though too much length can also result in pain. (Bumping into the cervix is, for most women, a rather painful experience.)
Don't do this.
Just use a good, random, password generator with decent settings.
Varying away from that just to 'change the kind of password' is only going to reduce your security.
You want as many random bits of information as possible in the password. That's it.
