The first scene [gallery 01, 02, 03, 04 & 05] of Ryan IV at Active Duty was released last November 2013 and his most recent scene was released last September 2014.
This coming January 23, 2015, his scene, as Brian Strowkes and as a top to Markie More, will be released by Next Door World.
Considering Active Duty and Next Door World are family since they are handled by Buddy Profits, I assumed no name changes will be done or just gave Ryan a last porn name.
