8th house stellium in composite chart?

There is a guy I'm seeing. Our composite chart has a very intense concentration on the 8th house- Sun and Mercury in Leo, and Venus and Mars in Cancer are all there with a bunch of conjunctions.

Then in the second house we have the Moon conjuncting both Uranus and Neptune.

Thoughts on these placements? I felt a connection with him immediately when we first started talking and we were really great friends but it was so confusing because I found myself irresistibly attracted to him and didn't understand why. Now that we've started seeing each other and I feel like I can't get enough of him. I've never felt this way before about anyone.
