Your best bet over here is to join some kind of sports club...cricket, rugby etc. They usually have club houses and plenty of events.
Weird health nut hipppies have ruined the experience at a lot of big box gyms, but if you can find something small and local, there's usually a positive, yet masculine atmosphere. Your friendly neighbo(u)rhood boxing gym might have what you want, with the added bonus of giving you dirty looks when you walk in for the first time. The thing is, in my experience these places have an existing social structure that may take establishing yourself as a regular to break in to, but that might just be because I have the social skills of a rabid badger.
Lol! Thanks Josh :)
