An article was posted on cnn.com about female orgasms.
In case you were wondering, most females need clitoral stimulation to achieve orgasm. The clitoris looks like this:

As a side note, for a variety of reasons you can usually find big clits on fitness chicks and female bodybuilders like these:


I’m not so sure that a bigger clit means more pleasure for the woman. It’s probably analagous to a guy having a bigger penis. It’s probably more related to how many nerve endings are in there and how sensitive the organ is as opposed to size.
I, Bert the RegularPervert, have slept with chicks with a variety of orgasmic tendencies. I had a girlfriend in college who was vaginally orgasmic, and let me tell you that’s a blast. She had a success rate of maybe 90%. She really liked being on top, which is odd since there’s really no friction on or stimulation of the clitoral hood in that position. Come to think of it, the very first girl I slept with had lots of luck in that position too. Looking back though, she was probably a faker and I was too green to discern the difference.
I was once engaged to a girl who absolutely positively could not come vaginally. Even going down on her and giving her cunnilingus only had about a 25-50% success rate. It took almost 6 months to figure out that if I snaked a finger around to tease her anus while I licked her. Girls, make it easy on your guys and just tell them what gets you off! What the hell, a link to anal play.
