Answer
This question is truly a first for me and I'm 59 years of age. I can't fathom a man going on strike because his wife won't give him sex more than once every three weeks. What in earth do you hope to gain by going on a sex strike?
Did you ever think that possibly your wife has some sort of emotional problem that possibly could be addressed by a professional? Is there the slightest possibility that when the two of you are making love, you think only of yourself and don't take her feelings under consideration, as that would make her not want sex with you.
Maybe the best thing you can do is sit down with her and openly discuss this problem you are having and hopefully the two of you can be honest with each other and find the root to this problem as pouting doesn't solve a thing. Try comforting her, don't yell at her and never point fingers. If all of this doesn't work and you are so frustrated that you can't stand it any longer tell her that you will have to take a lover and see what she says to that. Maybe she will agree with you especially if you aren't doing it for her in a positive way. Most women like sex as much as men, but only if the man satisfy's them. What's the sense of going to bed with a man or woman who can't or won't satisfy you. Maybe food for thought.
Good luck
