I hear a lot about trust and honesty being mentioned. That's all great when a relationship is healthy. But what happens when you break up with your girl or it's divorce time? If she wants custody of the kids or more of the assets than you think is fair is she going to squeal? Fucking yes she will tell everyone! If it was just a girlfriend she will likely still blab just to be a cunt. Are you putting her in a position where she has to lie to her friends and family? Why put her in that position? Tell your woman you eat like a horse and train with a passion and that's all she needs to know. It's easier to ask for forgiveness than permission sometimes. If grapes5 hadn't left his safe open he wouldn't have even started this thread. You can't be sloppy, forgetful, or careless with your important business. There isn't a lot of upside to being honest on this particular subject and a shit load of downside from my experience. I'm not suggesting lying is the way to go but you don't have to lie unless she asks specifically and that isn't all that likely if you mind your P's and Q's. Now if she is on gear as well then that's a different story but not all that likely for most guys. Deny, Deny, Deny, just like with your boss or your mother in law. Do you ask her how being fucked by other guys was? It's none of your business, you'd probably rather not know, and she probably wouldn't like to tell you. Same with running gear.
