M4M (30) looking for a no-nonsense key holder

I'll cut to the chase: I'm a compulsive masturbater and a sub.

I'm looking for a dominant key holder to keep me under control.

I've tried nofap but failed and I'm looking for someone who'll take a firm hand, allow me specific times to masturbate.

I'll follow tasks on the condition of no face shots and no posing. I'll send proof pics whenever you ask immediately.

I'm also looking to improve my fitness. I run every second morning and do strength training but I'd like someone who can take a firm hand there too.

Please DM me if you're interested.
