Missionary variations - I have an insanely sensitive g-spot and that's the best position for hitting it.
I'm really just obsessed with eroticism so most things can turn me on, though I especially like very masculine men who are assertive sexually, because I spent so much time in my life being dominant and assertive. Also, like many women, sex is very mental for me so I like to feel incredibly desired. If the guy is just expectant and whatever about sex with me, it's an immediate turn off and I won't go through with it.
