Well, you tried something new, outside of your comfort zone and found out it wasn't for you.
We have this very high end steak house nearby in a welthy neighborhood. it has 3 floors, one the dining room, a speakeasy in the basement which is pretty cool, where you would take a date for drinks, and the upstairs which has a DJ. Well, a few years ago we took a friend there for a 30th birthday when it first opened not knowing much about it. We went upstairs and OMG. It was the 45 plus crowd of men and women, the women dressed in the skimpiest clothes ever throwing themselves all of the guys, the guys eating it up, the women so drunk, one was dancing with a wooden pole in a very sexual manner. We just stood there and said "nahhhhh", and went downstairs to the speakeasy. God knows how many were married, recently divorced, cheating, whatever. I am all for having fun and not caring about what other people think, but it was kind of a sad sight. Definitely not my scene.
I have had one night stands (not many). One when I was 20 and the ex and I were "on a break" (as in he wanted to date someone else) a coworker had a friend, (who happened ot be hot as heck and filthy rich) and it was only the second person I ever slept with. I felt absolutely completely dirty. He kept trying to see me again, and I felt so awful, I didn't. I've had 2 others, one was a guy I had known through years, another a coworker. The complete stranger thing is what makes me uneasy.
It's funny, my ex and this one night stand were my only. I figured it would be just those two for the rest of my life. I hate in a way it is not.
I made that about me, somewhat, sorry.
Have you thought about a crossfit/group fitness gym where you work out with the same people all the time? That's how I met FF. But the best part was the girlfriends I made and the group events the gym did. I got into the best shape of my life too. Think about it!
