SockMonkey saidI want to find a new sport to play. Ideally, it would be pretty easy to acquire the skills to play it, have a lower risk of injury, and would also be something I could do with other people. The first ideas that occur to me are golf and racquetball. Can anyone recommend some more?
Consider volleyball. Within your own age group it's not too difficult, you're playing on a team with other guys just like you. Doesn't require a big personal investment, either. In some cases you may also get to play it nude, which I've done.
Height is an advantage at the net, but at a short 5'8" and your weight, both of which I've been, quickness also counts. Light, fast guys can cover more of the court better than some lumbering big guys.
Golf can be great, too. Does require a possibly costly initial outlay in equipment, and paying for lessons from a pro, since it's tough to teach yourself. But it's a very rewarding game, and in a place like here in Florida (golf capital of the USA), we have gay golfing groups. One of them founded by an RJ member.
There's also amateur softball. A lot of bars, especially gay bars, sponsor them, just ask. A display of trophies is a good clue. Many of the guys are not young, just having fun. Go to a game and observe. You don't have to be Babe Ruth.
Another club item is bowling. We have an entire gay bowling league here. But if you don't live in Gay Central, like this is, then look for any amateur league. Again, bars tend to sponsor them. Ask and look for the trophies. A bowling ball, bag, and bowling shoes, maybe a team shirt, aren't a terribly big investment, and it's as much about the socializing as the playing.
