I think having a woman around will only make a man bolder and prone to taking more risks whatever the activity is. It may be subconscious of course (sometimes) but I've read articles saying how men overeat like crazy on dates to impress women and they don't even know they are doing that because of a biological/evolution propensity.

This exact same thing applies here and I would say it would be a much stronger effect. One can only conclude that the consequences would be either total loss or the biggest jackpot of your life!
