So...
Your asking for advice on how to cheat and not get a nasty that might force you to tell your wife you cheated?

So, you don't want an STD because you don't want to have to tell your wife you got it from having oral sex- but it doesn't bother you to commit adultery or to ask strangers for help in doing so?

My only advice is to try to see this from the point of view of your wife, who married someone who asks strangers to advise him on how to betray her- but if your only concern is not contracting an STD so you won't have to embarass yourself by telling someone where you got it, I doubt you care that much about anyone other than yourself.

i agree with what everyone else has said..this is cheating..whether its with a man or not, you're having sexual relations with another person period when you are a married man..shame! stick to masterbation and dont do this...you do it once you may wanna do it again..stay faithful to your poor wife please...i'm sure she would be shocked and heartbroken to find out you had cheated on her...
