It's so frustrating when I have to continually stop & rephrase a sentence because the person I'm talking with can't comprehend either the subject or vocabulary. I'm a woman with pretty good intelligence myself. To be honest it is one of the reasons that I prefer women. Studies have proven that we have higher intelligence. The patriarchy held women back for so long that the "dumb blonde" thing sadly became thought of as appealing. I've even had teachers that told me growing up I would do better with the boys if I didn't show them that I was more intelligent. Of course I didn't care anyhow.
I have had potential partners who after one conversation each could tell it wasn't going to work because she couldn't keep up with what I was trying to say. I am a writer & love words. I even had one woman get mad at me because she thought I was purposely trying to act intelligent. It just comes, I do attempt to keep it at general vocabulary at first but as I relax more complex concepts & larger vocabulary flown in. I think it's better to get these things out of the way right away anyhow. In the first hour I also establish my interests, the fact that I only will practice safe sex, my partnership status, & that I don't believe in monogamy. If these things are issues then neither of us has devoted more time than necessary & can say we have had a good conversation while we move on.
