Welcome to playdip, Penelope!
I've seen you say hi to Pootleflump in the chatbox. I would talk to her more. She is from Scotland and has talked about Face-to-Face games in the UK, though many seem to be organized as a one-time gig and(/or) without multiple boards. I could refer you to others, but Pootle is more qualified to do so and I'll leave it up to her. I'll PM her.
Pootle is ranked #5 here and is an excellent player. I did horribly at WDC 2018, but used to be terrific at Face-to-Face and online. Durga, who's Canadian and from webdiplomacy, got 3rd place at WDC 2017 and she's currently the Tournament Director of the Online Diplomacy Championship. Kimpossible hasn't played Diplomacy for long, but she's really enjoyed getting into the FtF scene.
Some players say they treat women differently in Diplomacy, but I have seen little if any evidence of that in person. Also, I've heard little if any complaints from the five female friends (not including girls from playdip or WDC 2018) I've had who have played FtF Diplomacy locally.
You say that you've "played a lot of Face-to-Face games with school friends" though... I would say that I didn't notice much of a difference between WDC 2018 games and local games in terms of player interaction.
