Trying a 40 day challenge

My wife and I are holding off from sex to see if we can make it forty days without sex or masturbation. It has been 22 days and she claims she is feeling antsy but we are wondering if after the forty days we so much as touch a vibe to her she will go off like a rocket and I don't think I would last a second. I know this may be true for me but do women actually get more sensitive in this aspect?
