Hi Frankie
This sounds like a wonderful subbie experience! im 40 and didnt know i was a sub until last year when a little light kinky sex went further than we had planned and started setting of a whole loads of really heightened emotions. Now when i look back its clear i always was! This kind of obsessive feeling is very common from what ive experienced and discussed, suddenly you are experiencing feelings way beyond what you've known before, try and keep one foot in reality, stay safe and enjoy it!
