I've noticed that after my last lengthy banding session that I can't seem to get hard and my testicles are roughly half the size they were a couple of years ago when I did a 12 session, I always regret taking that band off could it be possible that I'm actually slowly but successfully castrating myself?

The only way to know for sure is to see your Dr. And have a blood work up including T count. Nobody here can make that call.
