i wouldnt if i was u..
she'll think ur gay, and especially wanting a 12" strap on..
A strap on is just that, it will leave you unforfilled and you won't be happy. Get some guy to do it, even if its not 12 inches, 8 or 9 will do just fine. The feeling of another man hanging his dick in your ass is something you will always remember.
You'll always remember it allright, right up to the point when you take your last breath and die from AIDS. God is punishing you unnatural sinners, may you suffer the damnation you deserve for being such miscreants.
God didn't create AIDS, people did, and I assume that you know 100% for fact that you are going to heaven?
Actually; it came from monkeys.
Find a man who is willing to fuck you and don't tell anything to your wife.
