Few thoughts:
nuglet - black sunshine is actually correct. I can't think of any providers that will let a second person, regardless of their sex, join in without a rate increase. Some rate increases are more than others.
silly_slut, again I have to agree with BS (loath as I am to admit it). Seabound just sounds jaded with both sides of the hobby. Guys like that can go either of two ways. Either A) he'll be a haggling douche who doesn't like himself or women very much and will try to overstay....or B) He'll be straight forward but distant.
The B type of hobbyist isn't bad by any means. He won't stalk you, he'll be careful so his wife won't show up a your incall, and he'll be more aware of the clock than you are. The downsides are the provider will have to pour herself into the session to get him to feel connected and actually have a have a real GFE, he might be paranoid so refuse to set the payment down before the session begins, and it's hard to get really, really into GFE if your partner isn't emotionally present. Thankfully a lot of these type of hobbyists just want a PSE mindset with GFE menu.
Which type a jaded hobbyist is super apparent before an appointment even happens.
SS, I do get where you are coming from, but remember that people who seem to always expect the worst out of others, regardless of who the parties involved are, have often been disappointed themselves. We all are a product of our experiences to an extent. That said, how positive our experiences are do have a relation with who we choose to surround ourselves with....especially in the hobby.
brentash - I'm 100% sure the vast majority of providers are completely fine with what you are looking for....as long as you understand that you are paying for the time spent not the level of activities partaken in. Find a lady known for being a great GFE. Don't go by what providers post in their ads. Figure out the hobbyist who you think isn't full of shit and ask for recommendations.
On Topic - Based on what I've seen, if CSB's current arrangement doesn't work out I doubt it will be from her misbehavior. She did react very professionally and maturely to what people said. A "loose cannon" wouldn't be able to help herself and would be firing back with
"U don't know MY situation. My SO luvs me very very much!!! " (Unless I'm totally out of the loop and she's sitting behind her WK's whispering in their ears to defend her. Somehow, I think she's beyond that.) I wish her and her SO the best.
