His Uranus-needs, Jupiter-needs, and Pluto-needs are expressed through his most intimate partnerships.
Whether or not he uses it skillfully or destructively depends on the aspects in HIS chart to those planets.
Your Venus is conjunct his Pluto. His Venus is opposite your Pluto. Neither of these are positive aspects. The relationship often has a compulsive quality to it, but also ends up becoming more and more a series of power plays .. attempt to manipulate each other through guilt, coercion, blackmail or sometimes even through force. Sometimes one person ends up being sexually disgusted with the other.
Your Venus conjunct his Ascendant indicates a close tie and bond, based on affection. Venus sextile Mars helps with sexual compatibility.
But this is not a man who commits easily (Uranus in 7th). His relationships tend to be unstable, and often break off suddenly or he cheats. Pluto in the 7th can indicate that marriage bring much self-growth, but USUALLY (especially if he has squares of oppositions in his chart, to Pluto) means that the person becomes pushy and controlling.
I see a strong attraction, but I also see a very unhappy relationship. Sometimes when we love ourselves, the best thing is to walk away from a bad, toxic situation. Otherwise, we have to hit rock bottom (and it can take years of unhappiness) before we walk.
Of course, you've only given us 4 aspects. That's only a small picture.
We don't use the signs for determining compatibility. The signs only indicate the style of compatibility or incompatibility. It's the aspects that show HOW two people interact.
