You are unusual in your responsiveness, I think Poppy. Personally, I find an orgasm tiring and distracting from the job in hand. If a client insists great but my raison de etre is to draw out and satiate the person who paid. Please do not think that I am criticising, I am not, but I would not be able to be so imaginative if I was concentrating on which angle got me off.
Hey we are all different, which is the beauty. No two men are the same, so why should we be? I don't see that many guys so for me having an orgasm is part of the joy of the work I do and personally I don't find it tiring or distracting. I don't find myself concentrating particularly either, as my body is homed in to the other person (most of the time) and part of the enjoyment for me is seeing their enjoyment.
I know what you do works and I know the way I do things works too, but again that is the beauty of our job. A lot of guys want variety and our difference provides that. I think if I saw a lot of guys per day then it might need to be addressed, but the majority of the time I don't, as it fits in with my normal life and duties as a Mum.
Lastly, I never focus on my orgasm, but I do encourage my pleasure and most guys seem to be more than willing to do that. I've been surprised at how many seem to be deprived of the joys of giving RO, or fingering and as long as they are happy to listen to my body or the odd guide, I'm more than happy to be aroused in this way.
I'm not saying that I orgasm with every client, quite a few don't want penetration and sometimes it just doesn't go that way, but then sex is not prescribed is it, there are no guarantees, other than you and I know doubt do our best to put a smile on their face and have them leave feeling on cloud 9, de-stressed and that they have had value for money.
