The biggest mistake a CD can make with his SO, is to not tell her until it is too late.
Edit: that site, crossdresserswives.com was not what I thought it was. Be warned. It seems to be saying CD's have psychological problems.
However the statistics the site provides are interesting:
"STATISTICS
8.5 million (approx) cross dressers in the United States alone.
30% (approx) of wives knew about the cross dressing before the marriage.
50% of wives found out during the first years of the marriage.
71% of wives were told by their husband that he was a transvestite.
10% (approx) of wives found out about their husband when he dressed up for them as a surprise.
16% of wives discovered their husbands female clothing.
5% (approx) of cross dressers gave their wives literature before revealing the truth.
90% (approx) of wives knew nothing about cross dressing.
Studies show wives were more accepting of cross dressing in direct relation to how soon in (or prior to) the marriage they found out about the condition.
The greatest sense of betrayal was felt by wives who found out after 10 or more years of marriage.
There are currently no statistics available indicating whether or not wives were told the truth that their spouse began cross dressing in early childhood.
Cross dressers start wearing female clothes in early childhood and their condtion is
life-long."
Of course they call it a condition. In psychiatry everything is a condition.
