I had my fair share of experience with femdom/hypno (not sissy and cuckold though - what I consider just one step further on this femdom ladder). Currently I have no problem with femdom/hypno anymore. IMHO femdom/hypno/sissy/feminisation is direct result of low self-worth and low self-esteem, nothing else. I would bet my dinner (and I am REALLY hungry) that you have also inner feelings of inadequacy (looks/body/money), shame and guilt (guilt in case you are also into BSDM). Good news is that based on my experience if you work on removing those negative feelings you automatically shift back towards more vanilla sex. So what I would recommend is to do the challenge and and also read following books in this order.
1. No More Mr Nice Guy - Robert Glover
2. Love Yourself Like Your Life Depends On It - Kamal Ravikant
If you recover your low self-worth any femdom porn will loose its magic (it wont make you hard anymore) because it would not be able to connect into your insecurities and exploit them.
