Kinsey was a noted researcher in sexual behaviour and had several books published including two books "Sexual Behaviour in the Human Male" and "Sexual Behaviour in the Human Female".

In his studies Kinsey found that more men than women reported fantasizing about sex, though women were as afar from being asexual in mind as in deed. Kinsey was especially interested in fantasy during masturbation. He found that 89% of men who masturbated fantasized but only 64% of women did, and men did so much more regularly.

I believe the figure would be much higher for women today just from my own experiences and through conversations with readers of my website. The figure will also be higher now because sexual fantasizing is considered normal and appropriate for both sexes. Plus anyone who knows me will attest that I truly believe that fantasizing is key to a healthily lifestyle and maximising the pleasure anyone can get from their own body.

To get further in to the fantasy topic it is interesting to note that although men still fantasize more during masturbation than women; there is evidence that women fantasize as much or even more than men during intercourse (I know I have had too when some uninspired man thinks he is making "sweet love" to me). I think the reason women probably fantasize more is because for most women the physical stimulation of intercourse isn't enough to bring her to orgasm.
