@BOomBoom31 You basically keep your options open. Have like 4 different girls that you rotate with - bi-weekly or monthly. This way that one girl will not stand out. You can rationalize by saying that she need not be committed to you since you are not committed to her. It works out in the end. Everybody gets butterflies in their stomach after a session assuming that the girl put in the effort, but then just keep a journal and make some private notes to yourself to describe the erotica, and it will eventually fade over time. You will be surprised when you re-read the notes a few days later (and then you realize it's a fleeting experience - just like having a nice meal at your favourite upscale restaurant).
I wouldn't recommend porn - only because those videos can alter your brain in a way that you will suffer from erectile dysfunction when you're doing the real deal. Keep your neurotransmitters under control. It took me a long time to do a reset - and I am happy to have recovered.
