*sigh* I don't know where to start..I'll try to break things down because I had a lot of *thoughts* when I looked at your synastry (some positive, some pessimistic)
First of all, you're one of the best sexually matched couples I've personally seen. I am not a professional astrologer (though I could get a degree in Pisces maniology LOL) and I've looked at several synastries, friends and family etc..
You have Venus/Mars *all* in close aspect to each other.. Venus to Venus, Mars to Mars, Venus 2 Mars double whammy. These are all easy aspects: trines & sextiles. It feels great to be around this person physically. Your bodies feel extremely comfortable and in-tune. Whenever you are in the same general space or room, you'll quite naturally gravitate to each other.
I can't imagine how perfect and satisfying sex would be for you BOTH - considering those aspects (and how close they all are).
__________________________________________
Now comes the (unfortunately longer & more complicated) pessimistic side of things..
Leaving sex aside - a HUGE dynamic between you in my opinion - is his sheer lack of earth and your dominance in earth. Taurus, being a fixed sign is a symbol of strength, staying power and ability to stand on your own two feet. Your Pisces is extremely watery.. All of his personal planets are in water. This is rather unusual, because a great majority of people will have at least a couple of elements represented at the Sun/Moon/Mercury/Venus/Mars level.
This tells me he is an unusual person.. in some way "special" - He probably has some amazing talents, whether musical or artistic. But he is also an extremely fragile person. Emotionally & Psychologically FRAGILE is a perfect way to describe him. It's very difficult for him to exist and carry on from day to day.. in this life that he perceives as mundane.. that he actually has no desire to be a part of.
I think the problems you are having might be that - this guy *needs* you, but he is not necessarily in love with you. Judging by your charts he definitely needs you to *survive* from day to day.. a lot more than you need him. You could easily become his proverbial "rock". A symbol of your relationship could be something like a sailor lost at sea in the middle of a storm - with the only thing guiding him being a particular lighthouse on the shore. You're the lighthouse!
Now that he knows you, he probably realizes how lost he was before he met you..
I'm not sure how else to explain that. Having no earth there at all and THAT much water.. It's extremely easy for him to get lost in depression, in drugs - in anything.
You seem like a "saving grace" from all of this - because with your Taurus stellium he sees you as the picture of stability.
This guy is far from being a survivalist.. His survival instinct is extremely low. But even so, I guess we all have an instinct how ever small to keep on keeping on.. and somewhere deep down he knows that if he is in the middle of a drug induced coma or an alcoholic fit.. somehow YOU could save him from himself.. because you're very stable - you're very realistic.. you're alive in the HERE and NOW.. whilst he often feels like he's not *all* here.
Another important side to your story-line.. is personal TO transpersonal differences. Wherever he has Pisces - you have Taurus. They are sextile which is good, but it is not the easiest sextile to manage. Transpersonal energy looks out to the world, the whole world.. the universe and beyond.. Whatever they do - they do for the world.. and not necessarily for particular people. As a personal sign - your Taurus nature wants something stable, grounded.. you want a man you can touch - a man who is THERE 100%.. From your perspective - this guy may well be a dreamboat.. not a "man" in flesh and bone.
Due to the way this dynamic comes across to me.. I would tell you that this is not the best guy for you. This is just my astrological opinion (and please don't take it too much to heart - I don't know either of you and there is only so much astrology can tell you. If you do want this to work as a relationship - ultimately anything can work - but I don't think this will be easy for either of you, and in particular for you).
I think you may end up feeling drained and used.
However, I also think this is a karmic relationship - and thus, on some level you have a "duty" to be there for this person.. and you *can* do that if you like.. but be extremely careful! There is only so much you can give - before you burn out. Make your boundaries clear and stick to them. This will not be easy for him to understand because he has no concept of "boundaries" at all.. so you may feel either physically or psychologically "invaded" by him at times (without your permission).
_____________________________________________
When It comes to the specific problems you are having (although I see these problems as the icing on a sizable chocolate cake..)
- No kissing
- Not enough sex
- You don't understand him..
The way I would interpret his behaviour is this: He needs you (as I mentioned). He knows that he *needs* you.. But he is not in love with you. At some point he realized that the sex and the kissing was leading you on.. He is sexually attracted and enjoys sex with you, but this (just like all his past relationships) - will probably not get serious - he is very much unable to keep a romantic relationship going.. In fact many things in his life may be started and never finalized.. not *only* relationships.
He probably does not want to hurt you so he drifts between leaving - so that you don't have to put up with his psychological mess in your life (and he probably has issues to spare).. and coming back because he is sexually attracted and because.. you make him feel alive - when he usually feels a little on the "dead" side.
The fact that you don't understand him and that he is not being clear.. is very typical of a personal sign to transpersonal sign dynamic - mainly when Pisces is involved (because the Neptunian Myst is extremely confusing).. I don't think there is too much to do about this in particular.. I'm not sure that you *can* understand him.. or that he is able to be *clear* on anything.
This ^ is another reason why I don't think he's the best guy for you.
_____________________________________________
My advice - after this very very long post is to do your best to always put YOU first.. If you feel things are getting out of hand.. If there is too much pain or aggravation.. love yourself enough to LEAVE.
If you think you can remain friends with this guy - and not get into something more sexual or romantic - that would be the best situation I can think of (but judging by your very sexual aspects, I'm not sure whether I can see this happening)
Don't get sucked into being his saviour.. You *can* help.. but not to the point where you feel drained.
I went to such lengths to answer this - because I am a little worried about you. As a triple Taurus girl – a personal sign (even if the Saggy moon may help).. you just aren't equipped to deal with this kind of mess. I wouldn't want this to take its toll on you in a very negative way.
Whatever problems he has - remember that they are HIS problems.. Not yours!
He doesn't want to kiss you? - this is NOT you.. It's not you being unattractive or whatever else.. It's him being basket case of ISSUES - issues that are incomprehensible to most people.. possibly including himself.
