His Moon is opposite your Moon - different emotional perspectives, upbringings, and security needs. His Taurus Moon may not know how to face the intense, probing depths of your Scorpio Moon. He may not always be as willing to go as deep with his own feelings which can lead to some conflict, especially because his Moon falls into your 8th. You really want to explore his emotional depths, his demons, etc. but he is not very open to this which can create tension. For you, a partner bearing his vulnerability to you is sexy and attractive.
