I found it interesting you dated a woman close to your own age and she wanted to bring a younger woman in. I was told by a Californian that women are all bisexual where he’s from. I bet San Francisco takes gayness to the most flaming level.
My girlfriend now is 65 years old and does not define herself as bisexual. Nevertheless she was in a 3 way menace a trois with this Alpha stud of about 55 years old, and she had sex with the other woman on a regular basis as part of this arrangement. She wasn’t particularly into it, but she was mostly just doing it to please him. You’d be surprised how many young women have sex with other women just to turn on guys. That’s what is behind a lot of this.
I’ve dated a few women lately who told me that they were completely heterosexual. I guess they hear it a lot because two of them told me, “No I will not have sex with another woman for you!” LOL I never even asked. I guess they just wanted to pre-empt me before I asked the inevitable question.
I talk to women all the time on porn blogs. The vast majority of them tell me they’re bisexual. But these are pretty hypersexual women. They even have their own porn blogs! Definitely a lot of women in my generation identify as straight, but it’s not unusual for them to have had sex with women a few times. I had a 50-55 year old girlfriend recently who told me she had sex with a woman once as part of a threesome as a teenager. Another friend of mine in her 60’s did it once as part of a threesome with her husband. And I had a 51 year old girlfriend who had had a two week affair with a lesbian woman. Most of them say something like, “I tried it with a woman and I realized I was straight/realized I was not into women/realized I liked dick/realized I wasn’t into women, etc. All of those women identified as straight. I met a woman in her early 40’s a while back who had regular affairs of flings as she called them with women. However, she identified as straight and not bisexual because she said relationships with women were completely insane, like on another level insane, with chaos and drama. The Female Principle is an unstable element but it calms down a lot if it is paired with a stable Male Principle element. On the other hand, in a lesbian relationship between two women, you have two unstable elements paired together, each one prone to chaos and drama. And the result may be exponential, so instead of 1 + 1 equaling +1, you might have +1 + +1 equals +5, or one unstable element plus one unstable element equaling +5 unstable element
