[MENTION=19719]Forever[/MENTION]
I feel that your behavior on here, from what Ive seen, is very characteristic of pisces merc. After all, interacting via text on line on a forum, i feel like you're going to see a lot of someones mercury. Pisces sees things in abstractions. This merc is known to have thoughts and ideas that seem very convincing and appealing, yet are wrong. It is natural for these mercs to get confused.
From what's I've seen, your actions seem be direct. You get focused on one thing to a high degree and become fixated on it. This is a Martian trait, Aries as much as Scorpio. I'm sure you know the stigma of Aries to become extremely fixated on one thing. This is very true of all Aries sins that I am familiar with, I feel that Venus in Aries functions in that same way as well for sure. I think its very reasonable to associate Scorpio with an Aries Pisces cancer combo in some ways. I'm sure what to say in response to what you said about your houses and the ruler of the planet in that house influence you? I don't look at that really, I feel like thats a very abstract thing to pay so much credence to. Im not sure I want to say that that is illegitimate entirely, its just that i feel like it should weigh a lot less than your actual placements...
My chart is fairly dominated by Aries Scorpio and Pisces as well and I share a good amount of the traits that you mention. I think that Scorpio comes with more of a sense of knowing, sureness, and finality in opinion from the start. If you've are familiar with any one who has a lot of scorpio placements (my wife has scorpio sun moon and mars in scorpio for example, they become sure about something around the time that they first think it). You seem to have a good idea of what's going on, but you don't seem to have the "knowing" that scorpios are renowned to have. Your decision making seem extremely back and fourth and contemplation with out decision. That its not Scorpio like.
As it relates to scorpio risings, a scorpio rising may not be as certain as a person like my wife, i do think that it is a scorpio rising trait to withhold when there is not certainty. For example, I was very very into astrology for years before I started to tell people. I didn't even start to tell my wife about it (like even the smallest detail) until around the time we were engaged. And even then I let things out very slowly. I feel like this in particular had to do with my rising sign coping with my own pisces merc.
And to touch on what you were saying about the women you are attracted to, that is such a strange an inefficient way to try and justify what your placements are. I think that your should focus more on your actual placements, dont think about houses or aspects, or anything else at all. Eventually work your self out on to them, but I feel that the actual placement is what should be focused on and fully understood before moving on the the next thing. You're focusing too much on what you dont understand. Start with what you know to be fact, try to make sense of it, and go from there. Thats my approach/advice/opinion - for starters. By the way, my intention was not to roast/shit on you so I hope you dont think that.
