How many genders are there?

@helenS That's why the definition of "masculine" and "feminine" varies with time and place.

@Sharon People tend to confuse "gender" (a social category) with biological sex.

@helenS I know but I try to answer the question that's actually asked.

Even biological sex isn't always clear. There's a difference between genital sex and chromosomal sex for example. You might like to look up Dr Anne Fausto-Sterling's work in this field. There is also an interesting article about the subject here - https://www.scientificamerican.com/article/sex-redefined-the-idea-of-2-sexes-is-overly-simplistic1/

@helenS Even biological sex is not as easy and obvious as it seems to those who believe there are only two.

@Sharon @ninalanyon Thank you both. 🌷
You are both right of course. Please note that I didn't say biological sex is, by its very nature, either female or male; I just said people confuse it with gender.

@helenS I wasn't arguing :-) just adding my two penn'orth.
