First off, I would like to welcome Belladonna to the CERB community. You seem to be a passionate person. I admire that very much.
I agree with you that it is easy in this hobby to get attached to and maybe even fall in love with the other person. As a hobbiest for many years, I have grown attached to many service providers and did miss them greatly as they retired or as they moved on to other things. However with time I have learned to understand my emotions. In general I am a caring person and I care for and appreciate most people around me including the older lady that serves me breakfast at a local pub and the SP that is much more intimate with me.
Where I disagree with you, is with your definition of GFE. We must be careful not to equate GFE with romance. There are some people who desire more than just genital simulation that leads to orgasm. Sex can be and for myself must be more than just a sprint to the finish goal. One of the most pleasurable parts of sexual intimacy is the experience of touching and being touched all over. For many, touching and kissing have great benefits such as feelings of reassurance, calmness and happiness. This calmness helps me to survive and to thrive in the busy world that I live in. So when I seek out a GFE, I am not on a quest for romance, but rather simply a more fulfilling experience.
