As I think I've said, elsewhere, much of the disruption and uneasiness you're feeling is not due to Saturn. Pluto is transiting your 10th house and is presently between natal Uranus and Venus. Meanwhile, transiting Uranus in the early degrees of your first house is roughly square transiting Pluto. Those two planets will cause disruption and upheaval in your self-understanding and in your professional and public life. Saturn is about to enter your 8th house where he is going to require you to consider other things.
The 8th house is not a house of love. It's a house of emotional exchange. Sex is in the 8th house, as is obsession, compulsion, addiction and death. We often refer to the 8th as the place of "others' money," but that's simplistic. I think it's more accurate to say that this is the house where we learn how and whether others value us, to what degree and in what ways. Inheritances are here. Resources we may call upon from, or may be required to pay to, others, such as alimony and the proceeds of shared property, are also here.
Sex and money are always linked, not only in terms of the value accorded relative to one's gender and sexuality, but also in terms of the transactional nature of sex. And so, while the 7th is the house of intimate partnerships, the 8th is the house of marital resources and other rationales for exchanging money for sex.
Liz Greene says that "The eighth house is a battleground, the primary purpose of which is self-understanding and self-mastery through constant crises" [Saturn: A New Look at an Old Devil, 26].
Saturn's transit through Scorpio and the 8th house usually addresses the individual's fears and feelings of sexual inadequacy, not in physical terms, but in emotional ones. "The difficulty here lies in the fear of submission, of violation, of the control of the partner, and of emotional rejection for it is the psychic rather than the physical exchange which contains the threat" [Greene, 27].
In your chart, with Mars conjunct Pluto conjunct Sun conjunct Mercury, all encouraged by Jupiter and Saturn moving through the place, you can probably have as much intensity as you can tolerate and some good stories to tell, at the end, too. Saturn will demand that you learn a lot in this house, I'd say.
Sex is easy. Even having lots of it is only as difficult as we decide it should or will be. Good sex, however, generally requires intention and attention.
