This is tough, because with the rate of divorce nowadays you never know what can happen, and her knowledge of your gear usage can be used as ammunition against you. I mean, some guys never know the magnitude of a bitch that they married until they flipped like a switch after a divorce. Some guys see it coming and hide their use. And others have ex-wives that can be compassionate and understanding enough to leave on good terms and not to bust you out.
Then during the marriage it can be a cause of conflict, if infertility or health ever becomes an issue, assuming that she is capable of accepting your usage. If not, refer to the above where she is now an ex-wife.
The more I think about it, the more and more selfish gear usage becomes in my eyes. Which is funny because some of us use it to make ourselves more attractive to our spouses, or potential spouses. I mean, a great body CAN be built without steroids, assuming you have a decent enough stature/frame, but I'm more of the attitude where if I choose to do something, I need to stand out above the rest and excel. Which, unfortunately in the world of fitness and our journey to a great physique, makes steroids part of the game for everyone who wants to be great.
