The venus/mars conjunction and venus/mars squares are attraction related from both ends.
Because your born quite close together, you've got a lot of planetary similarities with regards to the outers, your merc/neptune falls on his neptune, i wouldn't see this as being great, as in being able to relate to each other on a realistic level, your probably confuse him and vice versa.
Sun sextile suns nice to have, but then you also have sun sq saturn which can be a very difficult aspect to work with. You'll feel repressed and squashed by his negativity, and feel that he saps your energy. The aspect can produce ego conflicts and constant clashes of wills. He may be want to hold you back by making things more difficult than necessary, and it creates coldness.
I personally don't like saturn contacts in synastry, my friends has her guys saturn conjunct her venus and he never makes her feel loved, in her natal she already has venus/saturn conjunction, so he makes her feel even worse. Shes constantly having "the talk" with him about spending more time with her, or showing her more affection that's not just sex related....but it never happens, so now shes doubting her looks even more, constantly dieting and changing/trying to improve her image etc to try and win him over
Ive recently once again cut contact with a guy i have a mars/saturn conjunction with, his mars is on my saturn but its manifested the other way around, no matter how much i tried he was always cold and holding me back...so ive blocked him once again.
