If you check the classified ads in the free alternative entertainment weeklies found in many major cities, you'll find listings for massage or body work. This is where to go when you want a "happy ending."
I get hard every time my girlfriend scratches my back...does that count? Well, yeah, I've gotten hard from one of her massages before. I especially like the penis massages.
Yep. I'm a massage therapist, and the ladies report that this happens on occasion, but they just ignore it. Most people are not used to massage, so things happen, it's perfectly natural. Just don't ask for a happy ending, it's not only illegal, you'll probably be told to leave and will be blacklisted at that spa as well.
I looked all the way through this forum topic and did not see an entry from Al Gore. Surely he must have something to say on this topic.
