According to me!
U form a great relationship with your GF. Unless u need to dress all the time, or go out that way, u don't mention this "hobby" u dabbled in but don't plan to continue.
She doesn't mention her "experiment" with her female college roommate either!
Everything is super! U tell each other EVERYTHING that is important and/or relevent. So, U don't mention your web porn visits, she doesn't mention she bites her toe nails!
U love each other very much! U get married!
The first 3 years r your honeymoon. Unless u have kids during that period.
Next, u will likely go thru what the minister who married us called the, "Tunnel of chaos"!
Your marriage now requires effort, compromise, and possibly some very unpleasant conflicts! It's not much fun anymore, it's work!
U get stressed. Your desire to dress increases exponentially! Now, r u going to tell your SO what you're doing in private? Knowing it COULD be the last straw?
If you've never been married, then in your imagination, u may say, "Of course"! But, in REAL LIFE, do u REALLY want to make your life together THAT MUCH MORE DIFFICULT? Maybe u WON'T!
