i have found that most of my peers are married or with a significant other

what have you done to keep it secret

for those of you who have been caught, was it the end of your relationship

are you concerned about passing a std to your wife

have you considered bringing your wife along for a 3some

do you tell the provider that you are married

more to come.........

I am married, too.
I am discreet. Keep all this on a separate phone and email. Password protect all this, too.
Never been caught.
I'm concerned about receiving & passing along stds. Period!  I get checked approx. every 6 months.
Not a chance I'd bring my wife.
Of course I tell the provider. WTF do I have to lie about.

1) I am single. Apparently, that puts me in the minority here.  So what?  2) Keeping it secret?  I obfuscate like hell to family, friends, and to all in civvie world.  They just think I may have a girlfriend that I am keeping secret.  If only they knew...  3) Never been caught, and unless it was LE that caught me, it wouldn't matter, because I would just bullsh*t my way out of it.  4) STD's are always a concern.  5) I have no civvie LTR at the present moment.  If I did, I'd withdraw from the hobby (unless the lady was a provider).
