I like wearing women's clothes
When you wear women's clothes how do you perceive yourself?
I like to be sexy and to feel secure.
While you can do whatever you want, if you dress up as the opposite gender and like it then there is an underlying problem. It isn't normal to do that, and you may have dysphoria and should seek a counselor.
It's just harmless crossdressing and enjoying it.
There is nothing wrong with dressing like the opposite gender if that is what you prefer. While it is more consistent that people dress according to their own gender, it is not something that you have to do. It is great that you are confident enough to express yourself the way you want.
