I was 47, so don't give up hope!
I had a couple close calls when I was younger, but didn't let it happen. After my first time receiving oral from a guy while visiting New Orleans, let's just say I've been making up for lost time. You're never too old to have a happy childhood.
For that first encounter I admit I used craigslist. At this point I'm surprised I had the courage (or desperation) to do that. I was in a city a comfortable distance from home, and the opportunity was there. It took me a couple hours of reading posts, narrowing the field, exchanging emails with a few, and then finally settling on a winner. Wanting nothing more than to suck me off, he left my hotel room happy.
I later found the gay bars on Bourbon St, but couldn't bring myself to push past the guy in the speedo and cowboy hat in the doorway. That was a little too public.
Since then I've preferred more intimacy with a guy, and have checked out some of Seattle's gay bars (mild to wild) with a boyfriend. I'm not really into the city scene, but it was fun.
