its called respect mate!
i never go into detail but i will always say its a good service, so what more do you want, to sit there wanking allday over the finer details!
the reason some gentlemen don't go in to details is because they have respect for the ladies that they visit which is a good thing and fair play to the guys that don't go in to all the details after all its a lady you are spending time with you can still leave good or bad review without going in to all the nitty gritty details
