I have been aroused by the texture of rough plastic since I was around 6 years old. The smooth texture works, too, but not to the same extent. I've never had a full orgasm that way, though. I don't even vocalize when masturbating, if you can call it that. I do experience a sensation in the right organ, but that sexual urge only lasts a few minutes maximum. It's very strange.
I have never experienced an emotional connection to any human being until this year, when I have experienced a brief infatuation with a man earlier in the year and am now experiencing seemingly stronger romantic feelings for another guy who goes to the same college as me. The feelings, however, are very strong only when I'm thinking about him, not when he's actually with me. I don't know whether I will be able to express my feelings physically with him, because the emotion and the physical sensation seems to be very disconnected in my mind.
Anyway, does anyone do something similar with textures?
