Don't remember. It was almost 30 years ago.
In regards to the title of this thread. You don't want to tell someone. You're better of determining their opinion. The same gf would talk about something she said she heard on a TV show without expressing an opinion, or something she heard someone say. Then she'd gauge my reaction. Turns out both were kinky sexual interests of hers. But the way she brought them up gave no idea, other than the fact she mentioned them. But it did get me thinking.
It's a good idea. She wasn't taking a position one way or the other. I had another gf make a comment about something she saw happen at a party, a dog and a girl in this case. But she expressed disgust, so I knew where she stood. But if she had said something like, "you wouldn't believe what I saw." Then it could have been an attempt to get my thoughts without making a commitment.
The key is "plausible deniability."
