Just a few fun facts because I saw some general myths here. And because female anatomy is no where being taught in any school or university (not in biology) for some reason.
(I know this is off topic, please forgive me for the sake or knowledge.)
I don't have a dick, so erectile dysfunction isn't a concern.
Anatomically, women have erections, too so they can go through erectile dysfuntion just like men. But most of the clitoris is hidden in the body so you don't see it (just the glans peaks out, that's what we usually refer to as clitoris even if it is just the tip of the iceberg), but you can feel it. Additionally, in contrary to men a woman can have sex with a "soft clit" so it isn't as much of an issue, but she will feel less pleasure and is less likely to orgasm.
Another fun fact: viagra works on women, too!
Then ofcourse there are both clitoral and vaginal orgasms
Vaginal orgasms are a myth, too. The body of the clitoris is actually larger than the one of a penis and it is "embracing" the vagina from both sides
So the G-spot is probably the spot where the clitoris is easily reachable.
I know most people might not believe me, but I am not making things up:
When a person with a vulva is aroused, blood rushes to the erectile tissue that makes up the clitoris, causing it to become engorged. Here's how it works.
