My favorite Peter anecdote is the letter of the London owner of the house that Peter and friends rented while visiting England. It was directed to the Parliament, iirc, and was roughly "those rowdy Russians broke everything including the walls, now who's going to pay for this?"
(they were _really_ rowdy. Not just in London. Everywhere. Now Peter was no introvert, loved having bunches of guys around and playing rough jokes with them.
(also was maybe bisexual. Or pansexual. Or "will try anything". And had a bestest bff Menshikov, a groom's son he made a prince. They called each other Mein Herz, but Peter was not above beating Menshikov up if he thought he was stealing from the treasury too much).

Erm, sorry for intruding, but you linked these posts and I've been reading them for the last couple of days.
