I love questions such as this one.
I don't fully understand my Venus and Mars placements, even though I've put a lot of years into studying it. What I don't understand yet about my Venus placement is not a part of your question.
I have Venus conjunction Mars in Pisces, and I've definitely seen the connection of this aspect. It is a wide conjunction, and goes across the cusp of my 5th and 6th houses. Venus sits at the very end of my 5th and Mars at the beginning of my 6th.
I think this aspect gives me a great deal of energy and determination, because even though I think and feel like what is said to describe Pisces (Sun/Mercury), I don't relate to many of the negative traits said about Pisces Sun.
I think that Venus in Pisces in the 5th gives me artistic ability which shows up in many parts of my personal and work life. I don't have the predisposition to gambling or other forms of financial speculation which is predicted, because I prefer wise investments and safe stock. I hate gambling because I think it's all rigged. I have Jupiter sextile the Venus conjunction Mars, and that could be the key there. What it says about love of romance, entertaining and hobbies is very true. I never get bored for any long period of time because I have tons of interests and hobbies.
Mars in the 6th ... well I'm the poster child for this placement. I have a strong drive to work, and I've had careers in every field indicated by every planet in which Mars aspects in my natal chart. I have a strong work ethic, and I'm probably a workaholic. The Venus conjunction comes in handy there, because it helps me turn off most of the work stuff when I get home and want to unwind.
The Mars 6th placement is indicative of service to others, and that has reflected on much of my work ethic. In addition, I have always felt drawn to volunteer work. I spend much of my spare time doing volunteer cancer support for a large government organization.
I haven't escaped the prediction of health issues with regard to Mars in the 6th. I've been dealing with cancer since I was a young child. I've had several surgeries, mostly indicative of the 6th and planets in aspect to Mars.
At one point in my life, I realized that I could not continue to work unless I found some way to adapt to my health issues. I decided that there was nothing I did in my work that I could not do on my own, and I started my own business during a period of good health. That has worked out well. I plan A around the events which I know will probably happen, and I have plan B for the unexpected (Venus and Mars are square Uranus).
Based on my personal experience, I would definitely say that Venus represents what we need and Mars represents how we go about getting it.
