A visually impaired female is the same as any other female. In this case it might be a little different just because she can't sleep with you based on your looks, which means you must work a little harder. You have to spend time with her, and I'm sure it'll take more than a couple weeks or months to sleep with her, so if all you want to do is have sex with her, you should move on. However, if you really like her, she's like any other female when it comes to being turned on, and things will happen naturally. Just remember she's not going to be turned on by looking at you (which doesn't always help guys in the first place), so more talking and touching will probably be required (as it should always be in sex, which is about pleasing your partner as much as yourself).
A male can look for signs such as dilated pupils, increased touch or proximity, verbal cues, and physical responses like faster breathing or blushing to gauge a female's sexual interest or arousal. Additionally, verbal communication and active consent are important in sexual interactions.

Uhm... No. And that is really weird.
It means a person (most often female), is aroused and that, as a result, her genitals are wet.
Sexual arousal is not based upon emotional feelings for some people. Sexual arousal is merely a physical characteristic, displaying the desires of the human body to reproduce in the way that it was designed to do so. Some women who are raped are sexually aroused. There was no emotional attachment, but it was simply the bodies response to the actions of the rapist. It can not always be controlled.

There is some contriversy about this term, but to put it simply, a man who is sexually aroused by the thought of having female genitals of his own has Autogynephilia. You can research the term on your own and see the confusion.
