A dominant woman has some advice for submissive married straight guys:

First of all, we’re going to assume that if you’re married and looking for play outside of your marriage, you’re trying to cheat on your wife. Maybe that’s fair and maybe it’s not, but there are an awful lot of men who are in fact looking to cheat, so it’s not an unreasonable assumption to make.

What do you do about this? Well for starters, don’t cheat. How do you prove you’re not cheating? Be completely up front about your situation and ideally introduce potential doms to your wife. I realize that won’t work for everyone, but it really is the best way to convince a dom you’re not a cheating asshole. If you can’t introduce people to your wife, be prepared to get to know them really well over a long period of time before they’ll even consider putting play on the table.

We’re also going to worry that we’ll be treated like a dirty little secret. Some people do enjoy a bit of secrecy, but an awful lot of people are going to want to be acknowledged as an important person in your life. You don’t have to tell everyone you have a new dom and that you call her Mistress Lash (don’t do that, that would be weird), but what’s so bad about “This is my friend ____” or about just having coffee together with no kink once in a while?
