Thanks for your replies guys, they're really insightful...the best thing I can think to do is this. It's gonna be loooong guys, cause I'm not sure what kind of information you'll need here. Sorry in advance.
SP
I could probably live in my very own protective bubble, only letting those I'm close to in. Material security matters to me, I want to be comfortable, and by this I mean come home to a warm, furnished home, knowing I can afford to pay all my bills, and maybe have a little left over for a rainy day, I like surprising people with gifts. Oh, and this might seem sad, but I would always need my laptop in case I get bored.
After that, I can't say I care much for my physical needs, I just deal with them as and when. What puts me off saying I have SP is that my ISFJ sister who is definitely a 2 with SP and my SP ISTJ 6 and 9 grandparents are ALWAYS offering food and drink to people, and kind of pushing it on you, and I don't really have a thing about food, I just eat it, you want my food, I'll offer, take it, you don't... fair enough .
SO
I have a desire to be liked, my biggest complex and mission in life is to eradicate selfishness. However, I have no desire to join any groups, regardless of what my passions are, because I never give them as much time as I should, and I always become sidetracked by some project or other, which quickly becomes more important. This doesn't mean I do not act warmly to everyone I meet, take an interest in their lives, and have friends. I really dislike the way society discriminates so readily against people it decides, and then uses the media to back itself up. For this reason I value the beauty of each individual far more than anything society has to say.
SX
I become deeply involved in everything I do, I always want to know more. I used to be obsessed with things when I was younger, but as an adult, that faded. I value depth and intensity in relationships, but I get more intensity from music. There is rather more exploration in my head than in real life actually, because in real life if it gets too intense I'll pull back. I'm much more laid back than the sx doms I know, who seem to have a fiery, sullen magnetism. I am not aggressive, possessive or jealous, neither with friends, lovers nor family members and I don't want those people to be around me all of the time, because that means none of us would be able to have personal time.
Having said that I would definitely willingly give my life for those closest to me, whose needs I wish to serve before my own. I'd say I want to be the perfect wife, housewife, mother, professional, friend etc, but if I think if the expectations weren't at least partially fantasy I'd get depressed with the imperfections, I don't actually have any expectations of what people should be at all.
