Really don't think you understand the concept of "companionship" in this context. The fat ugly trollops who volunteer, go to church, go to bingo etc etc are no more interesting to spend time with than the fat hairy beer swilling blokes down the pub. I have lots of people - male and female - I socialise with through various groups and through work.
For me "female companionship" means something totally different - it means spending quality time with a very hot young lady that I fancy the pants off, can flirt with, and invariably of course also fuck. I for one get a buzz from flirting with hot girls. Yes of course it's not real flirting as I don't need to win them over to fuck them, just open my wallet, but for me it's still a great way to spend an evening every now and then.
Also as I said if you genuinely click with a regular WG my experience is that some will certainly be happy to see you socially for free as long as you are still regularly paying for sex. It's not something I ever came out and asked, just happened naturally so maybe it's just me and my amazing social skills - your mileage may vary.
You're wasting your breath. People here are genuinely equating charity shop volunteers (yay, let's give up an entire weekend in the hope of clicking with someone attractive while standing around in a shop full of old things!), random pub people (because that's companionship right?) with sexily dressed, attractive dinner dates who are focused entirely on you. It really is different strokes for different folks I guess.
And you don't have to be a 'pick-up artist' to get some sort of buzz from feeling attractive. The best times I've ever had with women began with her genuinely finding me sexy. The thought that the lady you're with wants to spend time with you and wants to fuck your brains out (even if it's in fantasy land!) is not to be sniffed at.
In fact most of what this site is about is whether or not the WG you're seeing actually feels enthusiastic about shagging you. If you break down companionship in this context; mutual attraction, flirtation, sexual chemistry, ALL of those things are what makes an awesome session with an escort too. The opposite is something we all loathe, someone who just lies there with their legs open.
Anyway Adultwork isn't probably the best place for companionship, neither is that site Dukes of Daisy (although worth a browse!). I found SeekingArrangement weirdly interesting. The thought of having a couple of students 'on tap' for £500/month each for some may turn out to be cheaper than actual punting. The companionship element being going out with them as well as shagging their brains out. The £6000/month girls on there though are clearly deluded.
