Stop speaking about sexuality as if it's all about sexual pleasure! We all have sex-it means male or female (that is not gender), in some rare cases it may be ambiguous, but the fact is a man's sex is male, a woman's sex is female. The question used to be: what is your sex? Not do you have sex? And the answer would be male or female. A celibate man or woman still has a sexuality because their sexuality is about more than sex acts.
