To Ron and All: When I had my first prostate exam, I of course became hard, and was highly embarrassed. No fewer than 3 doctor friends (a gay man, a lesbian woman, and a straight man) all told me "It happens all the time - and not just with the gay patients."
Near where I live there is a retailer of alternative adult entertainments and appliances, I went in to accompany a friend, and the shopkeeper assured us that while straight men rarely bought the realistic looking dildoes, they did like the vibrating wands and strings of beads. -Rick
