Instead of resolving, this question will track public opinion. 

Buy YES if you're Bullish (i.e., believe more people will AGREE with "Masturbation is good for you" in the future, than the market currently reflects). 

Buy NO if you're Bearish (i.e., believe more people will DISAGREE with "Masturbation is good for you" in the future, than the market currently reflects).
