Adding to my post which is already too long, so a new reply lol
I've had some good experiences even though they weren't organic/natural, too. I don't want to discount the professionals, it's just that I don't see them very often. About 75% of my sessions are with the average woman who offers (and advertises) massage, not those who advertise erotic massage or massage with extras, etc. The other 25% is with independent professionals where it's clear they provide extra services and that's their main job. I much prefer the other way around as I do like a good massage. With the professionals, massage is the "filler" so to speak far too often imo. It's lacklustre or they have little skill, and you're not really paying for that (you're paying for the time it takes, as well as the ending). Even when the massage is good, or they make up for it in other ways, you know what's coming, and when, and that's not usually my thing. I've found with the massage-first, woman-next-door types, they either really DO enjoy it (some even even get off on it - I've been told by more than one that's it's a bonus for them) or they really aim to please. A few of the women like this that I've visited in the last 4+ years are not much different than us guys would be if we were being paid to rub down nude women - kids in candy stores. Yes, they tend to be older (40+) and not models or porn stars, but some are, and I'm sorry/not sorry, just horny.
A 50-ish woman I saw twice a few years ago literally told me that this is her sex life, more or less. She's too busy for a relationship, not interested in casual dating, and is at a stage of her life where there's slim pickings anyway. She advertised massage, as well as esthetics, and had a nice little studio in her home. She offered extras to men she was comfortable with, and only after a first session was booked and she met the client at that time. She provided hand or breast release only, but allowed the man to either use hands or oral to get her off (I didn't partake in either, just wasn't feeling it. She also probably did more, I'm guessing, but she didn't come out and say it). And she straight up said she gets paid to have several orgasms a week, or as often as she wants, more or less, and by whom she wants. Imagine us guys being paid to massage women, some of whom jerked us off or blew us?
One another experience I had that was pretty awesome (but also kind of strange) was this woman a few years back. Maybe late 30's, okay looking. Haven't seen her advertise since then, so I think she was fly-by-night, or I started doing this just when she was finishing up. Found her on Kijiji, didn't ask about extras, though I was pretty sure it was an option. Anyway, very very good massage, almost put me to sleep. About 45 minutes into it, on my back now, and my eyes had been closed most of the time as I was really relaxed and enjoying myself. No mention of extras and I hadn't asked, so I just enjoyed the rub down and relaxed. She started doing my inner thighs, and obviously I got quite excited. I was draped, but she had moved it out of the way enough that I could feel the breeze as I tent-poled. I was pretty new to massage in general, and independent massage almost completely, so I wasn't sure how she'd react. I opened my eyes just a little bit to check on things, and sure enough, most of my shaft was "out there" and visible, with the towel really only covering up the head. I look at her to gauge her reaction, and I shit you not, her eyes were closed, head tilted back slightly, one hand was still working on my thigh, and the other was DOWN HER PANTS. She must have thought I had dozed off, lol. I watched her for a few seconds, then quickly closed my eyes, as I didn't want her to open hers and catch her staring at me. I was really new to this, there was no mention of any extras etc. I figured she was into risky masturbation or something, lol. Obviously I opened my eyes again, because duh, and she was still working on my thigh AND herself, but she was now looking at my shaft, which was rock hard now. I figured wtf, so I slowly moved the towel completely off of me, and started stroking myself. She looked at me a little shocked, but didn't stop and went back to watching. We didn't touch each other, just ourselves, both came, and that was that. Next time I saw her - nothing, just a good rub down. And then she was gone!
I've got a few stories like this, most of these women have come and gone, just did it for a short while and disappeared, whatever. But this is the sort of thing I seek out (but don't expect). When it happens, it's awesome. If it doesn't, I usually get a good massage at a decent price!
