Disclaimer: I realize that the majority of you are paying for a sexual service and that your needs should be met within the boundaries of the escort in question. That is the service I am providing.
However, that being said, I would like to call attention to what I like to refer to as "jack-hammering." This is basically extended penetrative sex and nothing else. You may be convinced that good sex requires only penetration and stamina--as well all know, women want a man who can last (I hope you can sense the sarcasm there), or perhaps it is purely selfish on your part, you do want to get your money's worth after all. So you pound your paid sex partner, over and over, squeezing in every possible available second. In which case, I am not a blow-up doll. I am not an object solely for your use.
Keep in mind, I do not think it is a problem, for example, if you would like to simply pay to receive a blowjob, provided you realize the skill and time involved in administering a good blowjob. And I do not think penetrative sex itself is bad. But if you are interested in engaging in a full range of sexual behaviour, please realize that "sex" does not simply equal penetration for as long as humanly possible. After awhile it is painful, un-stimulating and rather boring. If a woman is not turned on, she doesn't create those delicious lubricating fluids that can make penetrative sex so wonderful. So take the time to pay attention to things like kissing and groping and licking and nibbling and so on. If the first thing you're going for is penetration, you have skipped so many amazing, naughty fun things to do to one another.
While we are providing a very intimate service, aimed at generating your pleasure and satisfaction, we have emotions, and physical limits. So keep that in mind the next time you're with your favourite lady.
Happy pooning!
