The relationship between the Aquarius man and Scorpio woman is best left as friends. These two know how to communicate together and do so very well. This is their best trait. Outside of this the only thing that these two seem to do is get under each others skin. There is a negative energy that flows between them and they irritate each other constantly. Over time this can ruin their relationship as Scorpio and Aquarius are incompatible astrological signs.
Sexually, Scorpio and Aquarius are very compatible and have a lot of fun but this is usually best as a one night stand or friends with benefits basis. The Scorpio woman and Aquarius man do not get along well enough for it to be any other way, usually. The things they are looking for in a long term relationship is not what they each offer the other.
