I saw two pieces of media in the last couple days that made me think about the eroticism of mind-reading – and about how the fantasy of having one's mind read can be hot, but is totally unrealistic.
Maria Yagoda's book on bad sex, Laid & Confused, points out that good communication is the single most important factor in determining how enjoyable sex will be for both/all parties. One of the key barriers to better communication between partners is the romanticized idea that if someone is right for you, they will "just know" what you need sexually, and will give it to you, without needing to be asked or instructed.
Obviously this myth has harrowing implications when it comes to consent; someone can think they "just know" what you want and be totally wrong about that, which could lead to them doing things to you that you decidedly do not want. Further, knowing someone well enough to understand their psychology might indeed give you a hunch about whether, for example, they'd prefer to be more dominant or more submissive in bed, more active or more passive, more gentle or more rough, but a) you still can't know for sure unless you ask them, and b) that stuff is psychological and doesn't tell you anything about physical technique preferences. Sure, your new girlfriend seems to enjoy being dominated and ravaged, but does she like her clit touched in up-and-down motions, side-to-side, or in circles? Does she even like to have her clit touched at all? Stuff like this is vitally important to find out if you want to have good sex, and it's not the kind of thing you can "just know" before you talk about it or try it.
The other piece of media I stumbled across along these lines was a clip from musical comedian Daniel Thrasher. He depicts a female character written by a male writer with the quote, "I love shopping, and my boobs! Everybody dance!" and then depicts a male character written by a female writer with the line, "I know your thoughts before you speak them. You don't even have to say anything. Everybody dance!"
