How will Saturn in Scorpio affect my Scorpio Venus after Oct. 6th 2012?

With my Scorpio in Venus I have the same concerns. It will slow us probably down for a while, make us more suspicious and show us if need to chnage something. Saturn is really about change, and Venus is about what you value.

Remember, Saturn transits tend to bring problems to the surface. If you have loose ends in any area that Saturn hits, it cuts them off. As always, plan ahead. See where Saturn is going to hit, and take care of potential problems well in advance. If you happen to work in the arts, Saturn transiting in stressful aspect to your natal Venus could indicate a dry spell when your inspiration takes a vacation. Conversely, inspiration could be as strong as ever, but circumstances may prevent you from producing. The harmonious aspects (the sextile and trine) are usually quiet, stable times in relationships and financial matters. These periods are usually not too important. Saturn has its biggest effects during the stressful transits.

Helful discussion in this topic with many individual experiences:

God, Saturn’s really been all over me for the past year, or more. First it squared my Moon, Mars, Jupiter, and just when the clouds were finally starting to disperse, and I got to see a little sunshine, bam! It hits Venus.

And not just Venus. Right now it’s conjunct my Ascendant, but still in the 12th, and also opposing my natal Sun-Venus conjunction. And Uranus still being conjunct my Sun and Venus doesn’t do much help, either.

When it started to oppose Venus I reached subarctic temperatures, and I’d hoped the cold would only get skin-deep, but noo, not with Saturn. Turning all my close acquaintances against me and drying up the finance department wasn’t enough for Saturn. It had to get to the core, and dry me up completely. (…)
