Are you a relationship expert? How do you KNOW usually? I will tell you what I KNOW from experiences.
My first marriage? ENDED with the fact her whole family was part of a massive family sex ring. She also had a serious drug and drinking problem. Let's just say SWAT raided her house and arrested her brother, father, and mother for a total of SEVEN felony warrants. Yeah. I also WAITED ten years for her (both virgins) to find out she cheated 48 hours before our wedding night. I found out THE NIGHT we were together on our WEDDING NIGHT that I waited for....for ten years....and remained faithful to her. I found the strength to forgive....THAT. I think THAT was much worse than ANYTHING crossdressing related.
I've also found out many secrets in my current marriage, which I will not disclose since I promised her I wouldn't. They are MUCH more than just "I like to wear these clothes." As my wife says "I find it hard to deal with Jessica, but you put up with X and X and X without batting an eye. I know you love me so much, and that makes it so much easier for me to realize who cares if this is us. It is US, not them."
Bottom line, everyone has baggage. EVERYONE. Guys and girls. As I've said in another thread, there are people that have sex with knives with a cutting obsession/fetish. Those who have a fetish for filth, sex with food, threesomes, and even people obsessed with fire play. There are SO many things out there, and these are all COMMON fetishes found in couples. There are couples that make THAT stuff work, and enjoy life together.
I won't point fingers, but I think people who are asking "How can I deal with my husbands crossdressing problem" need to grow up. There are FAR much worse things that can happen in a marriage. Be happy you are both sharing love together, and you have someone who loves you so much, they share the most intimate secrets of their lives with you! Isn't that what we ALL are searching for? Isn't that what you will search for if you leave him? Another guy who shares his secrets with you? What you don't think about is what secrets await you THEN?
