Honestly, if they're x years younger but not annoyingly childish, they're probably alright. I know plenty of 20-something girls I'd rather shoot than sleep with, but I've also met 18 year olds who made me feel exceptionally childish myself.

You probably don't have the issue in the Borders, where the average teenage girl is now so damned ugly, you'd turn gay - if the blokes weren't also repellant.

The problem is, you think to yourself "I wish I'd met you when I was 20-something" and then realise they'd have been five. That's kinda offputting.
