I think it is quite low on the commitment side in terms of emotional commitment. For the girls, it is definitely better for them if they know you can commit to keep seeing them since they are getting some steady income, but TBH, you can walk away any time you like.Created an SA profile just to browse and have to say that it DOES look interesting. Would I be correct in placing SA equal or slightly beyond casual dating on the commitment scale? (a scale where an appointment with an SP/MPA would be at the lowest end (no commitment) with marriage at the highest end)? The absolute last thing I am looking for is regular commitment.
Shack's advice on approach is very similar to the approach I would take with an SP/MPA about private appointments. Like any relationship - courtesy and mutual respect go a long way. I've had 6 long relationships with MPA/SP's (two still ongoing) and these are relatively low commitment but mutually beneficial arrangements - likely lower on the commitment scale than SA (my assumption, anyway) - so long as you don't get carried away. What I seek are providers who are attractive to me physically (obviously) and where we have some sort of chemistry (both personality and sexual). For me this means they can make me laugh and share a similar sense of humour and have a less mercenary view of the business, oh... and give me boners. There has to be enough of a trust and comfort level to exchange real names, etc. So it's very much like a FWB, but with money exchanged. I've met at their places, my place, hotels, with appointments from a quickie in the back seat of my car (long story) to a few hours to weekend trips. YMMV. I tend to like providers who are natural and do not have the "provider" look (i.e. not an overly enhanced features, "stripper look") - so SA is very interesting in that sense. I saw a lot of good looking women in my quick browse. I do have to say that some of the absolute best hobbying sex I've has been through private arrangements so I tend to gravitate towards that objective, so may have to check SA out.
A word of advice: Even though they need financial help, many of the girls do not want to feel that it is strictly transactional. As such stop thinking of them as "providers". I know we are ingrained to think a certain way as long term hobbyists, but this is different. There are no guarantees of sex like with a SP. Try to think that you have to woo them. If they can pick up on that vibe from you, you will be the beneficiary. If you continue to think of them as providers, there is more chance that they will pick up on that and the results may not be as good.
