This is my thought on issues of CDs and their spouse................. if any CD or TS enters into any permanent relationship with a partner without telling that partner its really unfair, inconsiderate, self-destructive, dangerous, selfish etc, etc.
With the little knowledge i have in relationships a girlfriend might not know about your CDing, your male friends might not know, but when you are marrying someone it is your duty and it will be honorable to inform the SO.
CDing is not an easy thing to accept for so many pple even CDs themselves. So much stigma is attached to it and the risks of a CD being outed in the most unexpected way or a CD confronting his/her SO with issues of transitioning while initially the SO has no clue about the CDing its really a gross injustice to the SO. Likewise so many other things might crop-up during the relationship.
Its suprising to find out that some women are so much interested in effeminate men, "sissies", and men that crossdress some are even interested in transsexuals i mean interested in wanting to marry them so keep on searching till u find the right partner.........search hard and be brave you will definitely find beautiful women that like CDs/CDing for keeps as an SO.
Finally, I think it'll be fair and wise to inform the SO before entering into any legal relationship like marriage.
