RE: a woman pleasuring a man, a man in his twenties is almost all-ways concerned in his own energy, his own pleasure.  As men reach their 4th decade, their energy shifts and they are very into using their own power to pleasure the woman thereby doubling his own good feelings.  I do not please or pleasure so much as be an authentic guide into your highest expression.  I am a teacher of the soul's journey up the Ladder of Light.  I am into connecting your soul's desire to authentic expression of power into the matrix, you will go give up masturbation and take up daily cultivation, where your erection and orgasm energy lead you directly to energetic mastery.   Orgasm energy can be used to attract anything you desire.   The integration of this power into your  'Ka' (the ancient Egyptian term for the human energy matrix) connects your sex drive to your soul, heart and mind.    Yes, you will experience pleasure that is different than with a woman of 25, and yes, you will go away happy and refreshed.  You will also know more about sex than any of your peers AND you will have a few great tantra techniques up your sleeve.
