I had one interesting experience when it came to explicit consent. I walked to the date, she drove. No alcohol was consumed by any parties.
She offered to give me a ride home, which I politely declined, and then accepted when she pushed. I asked her if she wanted to come inside, and she said yes. I asked her if she wanted to come upstairs, and she said yes. We went up to my bedroom, did the deed, I asked her if she wanted to take a shower together and she said yes. I asked her if she wanted to go for round 2 and she said no. She left, shortly thereafter, and I was pretty confused when she told me she had felt pressured into sex and didn’t want to see me again, when I thought I had intentionally given her lots of opportunities to say yes or no.
I still don’t think I need to get a legally binding document agreeing to engagement in sexual intercourse, but that experience really demonstrated to me that an extra awkward question or two is better than the alternative.
I’ll add dancing to this list. It’s certainly possible to just show up, do the steps, and leave, but it’s an atmosphere where talking to people is very easy.
If you go to a class for a few weeks/months, you’ll start hearing about other classes, or events. You also might end up finding that you have other connections with some people who you dance with.
I speak from experience here. I’m not very good at people, started dancing for that reason, and my time dancing has helped noticably, according to an old, long distance friend.
