I'm a Libra ASC and a 26 degrees Virgo so this has been a powerful transit for me which started when I was 21.
I basically went from living with my parents and having them pay my bills, to living on my own, paying my own bills, and working 12-16 hour days everyday.
As far as conjunctions only...
I have a Mars and Sun conjunct in my natal chart (in my 12th house, but close to ASC) and when Saturn conjuncted both of these planets I went through some big time legal trouble. I was living like a care free teenager before the Saturn transit and once Saturn conjuncted, he put a stop to it instantly. I kept these legal troubles very secretive (12th house).
When Saturn conjuncted my natal Venus I was going through weird hair dying looks (I was experimenting with platinum blonde and I'm a natural brunette), and once Saturn hit I looked in the mirror one day and didn't know who I was so I stopped dying my hair.
When Saturn conjuncted my Mercury I was working on a project where I had to market/meet people at weird hours/try to draw people in to my project. This is the time when I had the 12-16 hour work days.
In the end, thank you Saturn for allowing me to grow up. Saturn is retrograde (as you know) in my first house, so I wonder what unfinished business I will have to tend to.
