When I teach the reproductive health segment of my class in Healthcare Management, I urge my students to remember that porn is fantasy; imitating them could be hazardous to your health. After all, when you get down to do the nasty with your partner, you are unlikely to have an attending physician to deal with potential injury or to give prophylactic painkiller the way they do in professional porn shoots.
The kids are dumbfounded when I tell them that watching porn can be akin to watching a Superman movie. Hello? Scripted movie with directors telling them where to put what and how long a thrusting time to perpetrate etc. *rolls eyes*
For those who does not wish to contract chlamydial conjunctivitis (an eye infection) from sex, avoid getting facials, will ya?
