birth rates are so low that there are very virile men who have to take care of more than one girl to help increase the birthrate.
I think you may be deluding yourself.
This question is a yes and no. Yes, I would be able to date two girls. I actually have dated as many as four at a time, but the idea needs some clarification. Seeing more than one person at a time is fundamentally different from being in a committed relationship. Which involves time. And disclosure.
An affair to the side of a real relationship can't last for more than a month, or things get too complicated too fast.
