Colloquially, GENDER does mean sex! Nothing else! Your gender is either male or female at birth. Yes, you can think it is whatever you want it to be, but physically it is the way you were at birth unless you have had it changed! Those who think your sex and your gender are two entirely different things are totally wrong! Now you may be a Transgender, or even a Transsexual, but if you have male parts you are, gender wise, a male!!
The Grammarical version of gender was dying out for many years, but apparently has been revived. Probably by those who want to have many different versions of genetic sex instead of just male and female!!
Unless you have the surgery, you are what you were at birth. Putting on different clothing, and changing the way you look and act can certainly make you appear feminine! But underneath you are still a male being. Only God, or surgery, can change that!
I am a male, and I love being one. Yes, I do love to crossdress, but there is no desire at all to be a woman!! I am simply a male Crossdresser!!
