"Mambo" emailed me with his situation. he writes...
"My wife and I have a good sex life. We've been married 15 years buy she refuses to reciprocate when I perform oral sex on her. Should I refuse to give her head until I get a blowjob?"
Now Mambo, the first thing that struck me here was... you've been married for 15 years! If, during that period, she has never sucked your cock, what chance do you think there is that she'll change her mind now?
Nothing is more tiresome for a partner than being pestered for some sexual service that they don't wish to perform. I think the fact she hasn't performed fellatio on you for 15 years is a pretty good indivator that she has no desire to do so!
Research has shown that in only 50 per cent of partnerships is oral sex equally pleasurable to both participants. Another survey revealed that while more than 70 per cent of women enjoyed receiving oral sex, 64 per cent didn’t enjoy giving it.
Some women claim they dislike giving oral sex as it makes them gag. Others simply may not have perfected their oral sex technique or even known what was expected of them. Some women complain that the sight and smell of the male genitalia is a turn-off. 
The golden rule for a happy relationship is that the sexual activities are acceptable to BOTH partners. You did say that you have a good sex life, so presumably your wife is willing to provide the sexual excitement you need (apart from a blowjob). I wouldn't advise spoiling that with talk of withholding sexual favors.
As I've said before though, the key is COMMUNCATION! Talk to her about it and see if you can find some middle ground.
