Ad Sense: Snoring Ad?

Is it a coincidence that of all ads, the one lands on my site is one for the prevention of snoring?  My husband would probably say “Nope! It’s destiny!”  So, is it unethical to click on the ads that show on my own blog site?  Not if the end result is if my husband stops poking me in the middle of the night for snoring.  Hmmmm….need to think about that one.
