Excuse me, I should have worded that better. If you request that your partner do something, in my humble opinion, you should be open to them asking you to do it yourself and not expect them to do something you wouldn't do yourself. Also, it may better the experience for both of you in various ways if you were to had once done the task at hand for your partner. However, if the partner has no desire for you to do said task, and they are willing to do said task, then there is no point in that you would need to do said task before requesting your partner to perform said task for you. *ahem* For example, my boyfriend had to perform oral sex on me, before my lips were going anywhere near his junk (it's a personal issue). However, when it came to licking his tasty anus, I had no desire for him to reciprocate the task or go first.
And I must argue that your example isn't really a good one... I wasn't talking about an expertise- I was talking about something someone has never done before. In fast food, the managers normally must be crew members before they are ever allowed to be managers. It's RARE that a manager will get a job without being a crew member first. This is for many reasons, one of them being that no one likes being told to flip burgers by someone who has never flipped burgers. This might not apply to what we're talking about, but it's what immediately comes to my mind. *ahem* That, and IT is pretty serious business. In my office, IT is like the National Guard or FEMA for computer disasters.
However, if we WERE talking about someone with expertise in these matters, I agree that it would be rather silly for the person with expertise in a particular sexual act to ask the person asking to utilize your expertise to go first. That's... Ah, well, all that comes before "THIS IS SPARTA!!!" Hahaha. But seriously, Knotts, I really hope I did not offend you.
*EDIT: Uh, and this reminds me of a question I had been itching to find an answer to: So, I heard somewhere that normally when doms go through a training of sorts (via mentor or a class or something along those lines) they must play the role of a submissive, and somewhere else I heard that doms should first have the equipment they tend to use on their subs used on them. Is this true?
