Yeah, this is familiar. I'll say more: at some situations people looked almost scared after abruptly discovering that I'm... a little bit smarter than they thought. The most funny example which I can recall, happened when one guy put me in his bed, being seemingly sure that I'm retarded.
While he led me to the hotel, where he stayed (with ridiculous excuse!), I was in the good mood and commented things which I saw around with excitement. Every time I did it, he sighed and persuaded me to go further leniently, like a kid, like: "Yes, yes, it's a very nice puddle, but don't you remember? We have to go further...", took me by my waist and continued to lead me. His reaction entertained me and made me do even more silly things and laugh even more every time when he talked to me like this. But naive guy seemingly thought that I'm laughing not because I find him funny, but because I'm stupid.
When we came to his place, he put me into bed (with ridiculous excuse again!) and started to do what he wanted with me. Yet, looking how I gradually but confidently took the initiative into my own hands during it, he started to... seemingly doubt that he was right about my imaginary stupidity. Yet, I remained merry and friendly enough, so he didn't mind much.
After we had done, I noticed something like: "I know, things are easier with me, than with normal girls" - casually, among other things, chuckling. He abruptly changed his facial expression and looked at me with weird, almost scared sight in response. I thought that he didn't quite understand what I mean, so I sit near him, patted him on his shoulder and started to explain patiently: "Listen. When you did and said < this thing > and < that thing >, I had no hard feelings. I just find it funny and couldn't take it serious. But many other girls would perceive these things as offensive. It's not beneficial for you, if they would perceive you as asshole. So don't do it with others, ok?".
He was silent for awhile and continued to sit with a face, showing weird mix of emotions. Then he finally asked: "Why?". Me: "Why what?! " He: "If you understand everything, why did you let me to do what I did?" Me: "Isn't it obvious?!! Because I like s***x!!!!! ". This shifted his expression into a scared side even further. And I told something like: "Don't think that girl can't do it with you just because she likes it, even if she understands everything. You're not SO bad in it! You should be more self-confident!" and started to hug him almost sincerely encouragingly like:
Poor guy didn't answer anything. To be honest, at that very moment, I didn't even fully realize, how mocking my replicas sounded. So I asked: "Is anything wrong? I thought, you had fun, too... if you didn't, I'm sorry." He just mumbled something, which was hard to understand, seemingly continuing to feel highly uncomfortable... so I just said: "Was nice to meet you. Bye!" and went home, leaving him with his confusion.
When I told about this case to one close friend, he laughed a lot and told that I performed epic trolling. Like, that guy thought that I'm an easy target, but ended up to be easy target himself and was used and mocked, and he kinda deserved it.
But the truth is a bit more complicated... I really forgave that guy for his attitude towards me due to my good mood. So I didn't have an intention to strongly humiliate him, I just wanted to tease him a bit, but accidentally overdid it.
Is there really no options for me, but being perceived either like happy friendly idiot, or like cynical and smart-but-in-weird-way troll? Why it's so hard to understand, that a real person is a bit more multi-layered, than these absurdly extreme labels?
