Hey. I've had a similar experience. I started getting addicted to straight porn. Then slowly got interested in bisexual porn when my brain was no longer receiving the same thrill with normal porn. Later on I got into gay porn, sometimes transwoman porn as well but very rarely. I haven't acted out in real life with real people yet, and hope I never will. But one thing happened online with a guy( a recovering pmo addict like me). We started sharing our experiences with porn but shared too much at some point, and it escalated to some form of sexting and pic exchanges. Fortunately we stopped, but it's quite hard to keep it that way. I'm hopeful though. U can find lots of people on this site who escalated much further and broke free practicing nofap. So can we!
