Thanks for all the detailed responses.
A lil backstory and how my perspective on this topic has been changing:
I'm on a solo trip in Japan for 3 weeks, decided to enjoy my time and go balls deep literally and figuratively in Japan while I'm here.
I probably seen like 25+ different providers during my 3 weeks here (I'm leaving tmr)
My first 10 or so experiences have just been me like i said in my opening statement wanting to enjoy my time and i never gave a second thought if she was enjoying hers.
After a week or so i started getting very lucky and some of the providers i meet would be super hot and attractive, you know how some providers as soon as you see them naked you're rock solid already? basically that feeling.
Anyways i started having this desire to pleasure her because i was so attracted to her.
When i think about it I'm pretty sure its me just wanting to get an ego stroke. The idea that i could pleasure such a beautiful woman would make me feel a lot better about myself.
Anyways so i start to try, I'm very unexperienced (not a virgin, but i never been in a long relationship where i was able to have sex regularly and get better at it, honestly i don't think i ever gave a girl an orgasm)
I understand foreplay is a huge factor, so i start off with very slow foreplay kissing, caressing her body, nipple play and kissing, and then i just asked her (since i know im not good at it) "Can you guide my fingers in your pussy, and show me how you like to be touched."
She was happy to and it was pretty amazing, watching her squirm and eventually come to a full release, it was definitely one of the hottest experiences I've had.
Anyways now im pretty much in agreement with most of you that posted that its definitely something i enjoy trying to do. I have a caveat of "only if im very attracted to her" but i'm sure that will change.
If anyone reads and is also wondering if they should put in any effort in pleasuring the provider I'd say definitely make an effort and try it yourself.
She will actually give you a better service and sometimes free freebies of sorts. I can't think of any negatives unless she is not very attractive then i can see why.
thanks for reading.
