Why do we get so turned on by Ariel? Um none of the other Disney princesses have a tail. Duh!

She's sexier after her transformation and naked from the waist down.

When she looks like this, how can't you?

Maybe THAT will answer your question
I MISSED that one

Because she is gorgeous, elegant, charming and sexy.

Exactly. What's sexy about Ariel is when she first turns human, that seashell bra is all she's wearing, and she's naked from the waist down.

There have been numerous polls done by many groups, including Disney, and Ariel has been voted the #1 Disney princess almost all the time.
Also, mermen are considered a major turn on to many women, so it's not just guys.

(that's not just my personal opinion)
Now I'm curious. Please elaborate. You referring to the opinions of other people? Or is there some sort of objective proof of this?
There is data that says the color red is a turn-on:

From what I understand, mermaids in general are considered very exotic, which is why many guys are turned on by them. Ariel being the most famous mermaid ever, and the prettiest of all of Disney princesses (that's not just my personal opinion), just draws attention to her even more.

I'm a guy and I think she's pretty, but I don't get horny over her.

You're right, and there's nothing wrong with appreciating an artist's depiction of beauty. If someone drew or CG'd a female image that looked attractive, people would take notice because they did a good job.

It's because she can't talk back for half the movie
.
Sexist jokes aside, why do/did so many women have a crush on Aladdin, Hercules, Tarzan, Flynn, etc.? Hell, I know someone who had a crush on Disney's Robin Hood.
Just because a cartoon character isn't real doesn't mean we can't appreciate their qualities and characteristics. We can imagine what it would be like to know them. It's nothing more than silly fantasy. Hell, Zachary Levi (Flynn Rider) admitted to getting a little crush on Rapunzel. Doesn't mean he has an unhealthy relationship with cartoons. It just means she has qualities he likes.
The only real difference between getting a crush on a cartoon character and a live action one is the medium on which they appear.
If you're happy and you know it, go sit in the corner and think about your life.
