Of erections
• Erotic Technique
From a review of A Guide To Getting It On:
Also, it was surprising to read that a hard-on is not all that determines when a man is aroused. Some come in the middle of class for no reason at all (guys know what I'm talking about), while the vision of Princess Leah in the golden bikini may not give them an inch. So, ladies, do not take offense if "Princess Sofia" doesn't come up to say "Hello" every time you expect. Just remember the importance of kissing, and things will probably work themselves out from there.
