One confusion I've recently hear fairly often is 'prostrate' instead of 'prostate'.
Ambidextrous but 'encouraged' at school to write with the other, as in my day, (giving an indication of age !), we still used fountain pens and it was very easy to smudge wet ink when scribing with the left. However, in matters of an intimate nature, left is predominant. Very helpful when lying alongside one's partner. She uses her right hand to arouse me and I use my left hand (and digits thereof !).
I have always enjoyed it, since the day I read about it more decades than I care to specify ! I've been fortunate enough to introduce two women to the activity. The first was my wife - we were both very inexperienced. The second was someone I met after my marriage ended. It turned out I was only her second sexual partner and her 'ex' had been somewhat controlling. Also, I enjoy combining the mouth/tongue actions with, hopefully, finding the so-called 'g-spot'. That combination, for me, is superb and, from the reactions I've seen and felt, very enjoyable for her !!
