13-14 years age diff is sod all. I dated a 23 YO when I was 44. I can tell you that when your out with a hot girl much younger than yourself, your social proof goes ballistic. I constantly had other girls blatantly giving me the eye even when we were out together, and almost every girl we would pass in the street would try to make eye contact with me.

In your small town the most likely result of you getting it on with this girl is that loads of others will suddenly get interested. I think it was mystery who said that social proof is the closest a man can come to growing tits, it really is that strong an effect.
