The planet Venus in you chart tells a couple of different things. It shows where you attract things easily, how you act within relationships (romantic and non-romantic) and deals with your personal resources. It deals with the finer luxuries of life, but can also deal with vanities. So lets take a look at Venus through the signs and houses:
Aries/First- Self-centered at times within relationships, you are still generous with partners. You love the beginning stages of a relationship, with the butterflies, and you keep it going with lots of spontaneous activity. You are more likely to earn more resources, if you follow through on your high initiative capability, but watch out for splurging, as you are prone to spur of the moment purchases. Try to not jump in to financial deals, carefully weigh the risks.
Taurus/Second- Sensual in relationships, you are a true romantic. As far as priorities go, love and security are at the top. You enjoy the finer things in life (especially food) and surround yourself with beautiful things. Your hard work ethic makes it easy for you to obtain a higher income, and you are thrifty, always looking for a good deal.
Gemini/Third- The same thing everyday is not the way to keep you happy. You are excited by variety, which may manifest as multiple partners, or very spontaneous activities. You require a partner who stimulates you mentally, and you can be quite flirty in general. Watch that spending though, as it will deplete your money sources. Many people with this aspect will balance two jobs.
Cancer/Fourth- Love can be emotionally gratifying or heartbreaking, as you are super sensitive regarding matters of the heart. You give all of your heart to someone, and only move forward when you feel completely comfortable with the situation. You do have a tendency of mothering everyone, which can become detrimental if it turns in to "smothering". This can also affect your need for security. Financially, you may gather resources through savings and home ownership.
Leo/Fifth- You tend to become the center of attention, whether you meant to or not. People are drawn to your warmth and energy. You enjoy the social scene. In matters of the heart, you are loyal and passionate. You have the ability to make much money, which satisfies your need for socializing, but be careful with money matters.
Virgo/Sixth- Venus in Virgo natives tend to be picky and idealize any partners they have, which can often set them up for disappointment. Many people with this aspect actually choose to remain single. In a relationship, you can be caring and sensual, but sometimes, you can become the force that lets you partner get away with their shortcomings. Emotionally, you analyze your feelings, with the emotions and thoughts being so intertwined, it might be hard to tell which is which. Like Taurus, your work ethic provides a higher than average earning potential, but watch out for impulsive buys.
Libra/Seventh- Venus in this aspect gives the native the need for a partner. You may mistake the need for partner as a sign of love, so make sure you look at what your motivations truly are within a relationship. You seem to know what makes people tick, giving you extra insight in to those you associate with, which helps you to avoid conflict. It is important that you surround yourself with comfortable things, and luxury items, as you enjoy the more aesthetic parts of life.
Scorpio/Eighth- Chaos surrounds your relationships, often because any insecurities trigger negative traits, like jealousy. No one really knows what you are feeling deep down, as you hide it well. Tight with your money, you know how to manage it well, and you have higher earning potential with this placement. Very protective of those you love, you never forget a slight from someone who harms you or your loved ones.
Sagittarius/Ninth- Not one to be tied down within a relationship, you leave one the minute you feel that being threatened. It is important that you have partners that allow you to do what you wanna do. Very outgoing and optimistic, you generally do not care about financial matters, you feel like you somehow always have what you need. Save up for periods when money is tighter.
Capricorn/Tenth- Only complete security will allow the Capricorn in Venus native to show their affections. They are very private, never engaging in PDA. Sometimes, they might enter in to a partnership for status or financial reasons. You're conservative nature blends in to the financial realm, and your hard working nature can bring about money, although watch out for spending, just to prove you have it.
Aquarius/Eleventh- Aloof and distant, but interested in people, you generally tend to stick more to friends, although your ideal partner is a best friend. Like the Venus in Sagittarius native, you need someone who can let you be independent, and embrace your quirkiness. Often erratic in saving versus spending, try to set up a budget will help to stabilize this area of your life.
Pisces/Twelfth- Sensitive and a romantic, you are often lonely without someone else to share life with. Sentimental, you remember all of the big moments within a relationship. Often, people with this placement need someone else to manage their budget, often ending up in debt.

So what if Venus is retrograde within your chart?
It may not allow you to come out of your shell fully. You only let yourself completely out socially when you are 100% comfortable with those around you. You might doubt the affections of others, become completely absorbed in relationships, and not feel that others feel enough for you. You also may feel that relating to other people is awkward, and not natural.
