Sp/Sx: may use sex appeal to attain financial stability and comfort (think super model)
I think it's also "I work hard to build his own confortable nutshell before I look for an intimate guest"
Sp/So: may use social graces to attain financial stability and comfort (think social climbing executive)
Yes.
Sx/Sp: may use financial means to increase sex appeal (think cougar or sugar daddy)
Sx/So: may use social standing and status to increase sex appeal (think stereotypical alpha male)
The thing is that social status and financial gain are often linked to each other. My avatar for example, was totally a sugar daddy but he was a pure Sx/So, though he became rich only when he became famous. Sx/So is more "I gain sexual power and money toward a social status but I don't care too much about the money, rich or not, I barely change my extreme lifestyle", while Sx/Sp is more "I gain sex and social position because of my money but I don't care too much about the social position, popular or not, I still be a one-man-storm, an island".
Sp/So is more "I'm in a very good position of wealth and social respect, but i don't put too much energy in the sexual realm"
So/Sp: may use their survival and financial means to benefit the group (think person is a position of service)
It's also: I'am an agressive social climber, and work well for a stable position, but my sensuality is awkward.
So/Sx: may use their sex appeal to gain social status and acceptance (think fraternities and sororities)
Or supermodel: Gisele Bündchen, Adriana Lima, Alessandra Ambroisio, they are So/Sx/
So/Sx is also: I'm popular and charismatic and my sex-appeal and sense of individuality help a lot, but when it's time to care about my safety, I'm infantile, tough I'm quite addictive, I'm not very addictive.
