What my sister good girl said X infinity!!!
Sub Frenzy is very normal and isnt just for new people to the scene eaither, it can sneak up on even the most experienced submissive.
As for creepy or not,, Red flags go off for me too just reading your post about him khulmz. It is all too easy to be lead into a false sence of trust as a submissive. I myself have even suffered greatly by putting my trust in the wrong hands before and am very lucky to still be alive becuase of it.
I can't stress enough: Saftey first...Kinky second.
