It kind of goes hand in hand with sharing other aspects of your life - intimate details……….if the relationship has reached a stage where you can share your feelings about sex, kink and variations then there is a world to explore.If you reveal yourself to be a Crossdresser and your partner is not shocked or put off at all then you might just have the opportunity to say “but wait, there’s more”!
You have to read the signs though. If your relationship is not going to last if your partner does not react well it probably doesn’t matter although it could make life difficult if you have mutual friends etc.
