What are common phrases used when you sexualize the conversation?

Let's say you and her are basically strangers.

If she likes dancing you could tell her "you have strong legs" or something, and that implicitly points out you want her - without alerting her ASD.

The above example is just one type of example. There indeed are many more that are either commonly used, like asking her for some drinks or a movie(IMO that one's already explicit).

In addition, how do I advance if we do not have any chemistry, but I do like her body?
