Being distinctly funny isn't a requirement for me, though playful and cheerful are two important qualities that I usually seek in a girl.
I've never heard of this before... and I honestly wonder how could some smoke enhance his sensations in any way.
It depends what you do with the cam...
I wouldn't recommend inserting it in your ass, for example. This could be traumatic both for you and the person on the receiving end.
I wouldn't call it a turn-off per se, but tall women (5'8" and over) don't usually catch my attention as much as shorter ones. It's weird, but as much as some tall women can be extremely attractive (ie. supermodels), it rarely crosses my mind to approach/date/fuck them. It's often reciprocated however: I'm 5'9" myself so I doubt that a lot of tall women would consider dating a guy of my height, and thus that can be quite a deterrent to try anything with them. It's a bit like we naturally exclude each other in the whole dating scene. And I do have this whole 'must date someone shorter than me' mindset, just like most women have this 'must date someone taller than me' one.
It did happen that I dated and slept with girls that were taller than me though. Funnily enough, the girl that took my virginity was actually much taller than me; and I also had a lengthy friends-with-benefits relationship with a gorgeous 6'0" Romanian girl in my mid-20s. So yeah, tall women aren't necessarily off-putting, but the mutual attraction/connection usually isn't as strong.
