Hello nubivagant: I see this is your first post here on PC. So...

to PsychCentral… from the Skeezyks!

May the time you spend here be of benefit.
With regard to the particulars of your post, I have to tell you that this rings so many alarm bells for me that I have to be careful not to overreact.

The one thing I think I can safely say is that sex addictions & fetishes are almost impossible to break. Add to this the fact that this man appears to have no boundaries whatsoever. And my recommendation, for what it's worth, is to put as much distance (both physical & virtual) between yourself & this man as possible as quickly as possible. My personal opinion is this is a train wreck looking for a place to happen!

(Sorry if comes across as being too strong.)
PsychCentral is a great place to get information as well as support for mental health issues. The more you post, & reply to other members’ posts, the more a part of the community you will become.

Plus there are social groups you can join & chat rooms where you’ll be able to connect with other PC members in real time (once your first 5 posts have been reviewed & approved.) Lots of great stuff! So please keep posting!
