What Venus does in a chart
Venus is the part of the chart that answers one question:What do I find beautiful, and how do I show affection? It describes love style — not events, and not outcomes.
What Scorpio does to it
Scorpio is a water sign, so it moves on feeling and atmosphere. It is also fixed, which means it holds things. Put those together with Venus and you get loves completely or not at all — intense, private, all-in, applied specifically to love style.
Scorpio is ruled by Pluto, so this placement tends to be coloured by depth and transformation as well.
The useful version
Placements are not verdicts. This one describes a default setting, not a limit — the things listed above are what you do when you are not thinking about it, which is exactly why noticing them is worth something.
