There are two things you need to take into consideration here:
1) the frequency of sexual interactions with your wife
2) your ability to turn the sexual arousal program in your brain off
Has your wife always had a lower sex drive than you, or are there other things influencing this? Do you have young children? Do you have a sexual problem such as premature ejaculation or erectile dysfunction (which makes sex unfulfilling for both of you)? Is she tired from working long hours? Does she have health issues?
It's easy enough to control the sexual arousal program in your brain - just Google end sexual frustration. The bigger challenge for you may be to address the contributing relational factors.
