The percentage of women who can have an orgasm from intercourse alone is well under 30%. The problem simply being that there is not enough clitoral stimulation. That is why it is important to be able to take your ¡®Manus¡¯ which is Latin for 'hand', and simultaneously stimulate the clitoris concurrently with penetration. The motion for stimulation is generally a circular brushing of the clitoris. Depending on your position this is not always an easy thing to do. Practice different positions and find which ones are suited for manual stimulation. You can combine this technique with any of your normal lovemaking rhythms. If you are gentle and smooth, 9 times out of 10, your efforts will be appreciated. For positions in which you are unable to reach the clitoris, try and help your lover feel comfortable about touching herself while you are inside her.
