First step is to look at some priorities.
You have mostly easy to get along with houses and literally the only frictionful house is your 10th. You MH, Saturn, and to a small extent the Sun are your high friction planets. You do have an out of bounds Uranus, so in all your interactions, your personal freedom always comes to the fore.
You have a low latitude moon so you aren't going around demanding that everything be done your way.
Your boyfriend has the more difficult chart for relationships of of the two of you. His 1st and 6th houses are high friction, and his ASC, Sun, and Saturn are also high friction.
So in synastry we look at several things, to start:
1. Your high friction planets in his high friction houses
2. His high friction planets in your high friction houses
3. Your high friction planets aspecting his high planets
4. High high friction planets aspecting your planets.
We can look at the places where things go well, and in a full analysis that is an important step, but people generally already know that stuff, and in any case that part will just enhance your relationship, but not sink it.
Your only high friction house is your 10th. The only planet of his in your 10th is Pluto. Pluto is very low friction for him and only moderate power. It will be hard for him to be set off by you, but his Pluto can set you off since you can be touchy about your career issues. He can have a transforming impact on your career and professional issues---usually to the good. He will try to manage or help you remake issues there, and if your 10th house was lower friction, you would accept it more; this would be more so if you work together in some way.
Your Out of Bounds Uranus trines his Mars. This is a generally good connection where his energy and initiative will spur on your innovation. it also indicated sexual attraction. But because your Uranus is out of bounds you will always want your freedom in doing it your way and this may stress what is normally a good relationship.
You have no planets in his 1st house which is his highest friction house, but you do have three planets in his second highest friction 6th house. The most difficult of these is your Sun which is a friction event and is also conjunct his Sun. His Sun has moderate power and high friction.
You Sun should bring vitality to his career, job, health and general self-improvement. But because his 6th house is so friction producing, he may fight the kind of vitality that you are bringing to these areas. He amy wish you would mind your own business even though you are well meaning and believe that he needs your assistance here.
The conjunction of the two Suns with both of them in a friction level may cause you to understand each other, but at the same time try to be the star in the relationship. Neither of you will want to ever take a back seat to the other. This problem may start out as a little itch but eventually it tends to get really difficult. And the fact that its taking place in Virgo is likely to make continuous little things, Virgo is a high power and high friction sign for him, and very high power for you.
You may tend to goad each other on, and it can be destructive for both of you.
Your Strong and low friction mercury is also in his 6th house. This can be good for communication about work and health, and with your good skills in this area you will certainly want to share. The problem is that his sixth house will be less interested in hearing from you about it. Little suggestions may go on deaf ears, or little suggestions may not be received with the same nice way that you thought you gave them.
We can look at more tomorrow.
