A big part of this book talks about the importance of giving a girl vaginal orgasms, especially continuous vaginal orgasms. In my experience, some girls are capable of these type of orgasms, and some are only able to have clitoral orgasms.

Do you guys think that all girls are capable of these more intense types of vaginal orgasms? If so, how do you get a girl to that point if she's only experienced clitoral orgasms?
