I agree that clients over the years have come to expect more services. When I first joined the industry there were still women around whose main years were 80s/90s and even kissing was rare let alone full GFE, pretending to actually fancy them stuff, unless you were a very high end expensive escort. I had a guy actually email me the other day bemoaning my price and telling me to lower it to give 'ordinary guys a chance', as though my pussy ought be some kind of charitable facility.
So yea, I don't think 100 for oral and cim is unreasonable at all, I think even today that is a competitive price. But at the end of the day its not about what I think, but whether you can make the money you need to make in the time you have, offering the services you are willing to offer at the price you'd like... and if you can, that is all that matters.
