It seems that some in the med. comunity beleive...std's as in Chlamydia, NGU, Gon., Trich. or any std that is spread by body fluids (other than blood) are more easily spread by hand sex as opposed to oral sex. This is not to say that they can't be spread orally. Example is: Female masterbates and gets hand wet, then masterbates male. If infection is present...may as well stick it in uncovered. Same results with male wetting up and then rubbing own member. Vica versa male to female too. At least these won't kill you. Be careful though. Your wife may kill you if you carry one home.

Did ya know the Hep B virus can live up to 4 months on an inanimate object?   HIV...dies really fast outside the bloodstream much harder to contract....easy to contract in vascular areas like your booty canal....Just use common sense.

Just remember, we are living in a society that believes sex between two consenting adults is sinful. Puritanical beliefs state, "If it feels good then, it must be Bad" and humans should not pursue it without it being sanctioned by a higher authority.
