A side comment in Passionate Marriage mentioned that a surprisingly (to me) small percentage of women orgasm from intercourse alone. I have a feeling that my sample may be biased. So I'm curious...and please pass this poll along to anyone you think might be interested in
Just to be clear, I'm talking about orgasming from this stimulation alone, without additional activity in any other erogenous zones.
Oh, and please restrain yourselves from quibbling about my highly-scientifically-determined questions, polling methods, or sample population. I really don't care.
