I would like to think that the stache prompted this.
I was seeing a 17-year old some years back and that was a disaster, which put me off dating at all for a long while, especially women many years younger than I am. Since then I’ve been interested in women many years younger and older than myself. The numbers become irrelevant when two individuals share a certain level of maturity and similar attitudes.
So, the youngest I would date? That depends entirely on who we’re talking about.
