This is the sort of question that folks at the Kinsey Institute for Research in Sex, Gender, and Reproduction try to answer with surveys and stuff like that.
"Sexual Behavior in the Human Female" was first published in 1953. 60 years later, they are still publishing more studies and updated reports. Examples:
Herbenick, D., Reece, M., Schick, V., Jozkowski, K., Middlestadt, S., Sanders, S., Dodge, B., Ghassemi, A., Fortenberry, J.D. (in press). Beliefs about women’s vibrator use: results from a nationally representative probability survey in the United States. Journal of Sex & Marital Therapy.
George, W.H., Davis, K.C., Heiman, J.R., Norris, J., Stoner, S.A., Schacht, R.L., Hendershot, C.S., and Kajumulo, K.F. (2011). Women's sexual arousal: Effects of high alcohol dosages and self-control instructions. Hormones and Behavior, in press

Many younger women have a "Ewww" attitude toward cum that isn't shared by many older women. Women's sexual attitudes often evolve with age and experience. And what experiences they have are very important.
When I was a young wife, I would only do covered BJ. I was shocked that my older friend let her husband cum in her mouth! Ewwww gross! She assured me that it tasted like egg whites and you just spit it out in the toilet. So, I tried it. Yep, egg whites... then in the toilet. My husband was the only man I'd ever been intimate with.
It wasn't until I was divorced and had a lover "teach me" to love to drink and swallow his cum that my attitude toward it changed. But this craving had emotional roots... I was in love with him and wanted to please him. He would stroke my hair while I was sucking his cock and say, "You love the taste of my cum, don't you, baby? You want to drink it, don't you baby?" He psychologically programmed me, really.
My husband never did that.
There is no reason for men to think women would naturally want to "drink cum." Women just aren't wired that way. It has to be taught. And some women just never get over the "Ewwww" attitude. Some do, civvy or not.
