Venus rules both Taurus and Libra and is universally associated with love with its symbol often used to designate women. Its influence is broader than that, but is generally positive with Venus considered a benefic planet. Other areas affected besides relationships include comforts of all kinds, e.g. food, clothes or your home and work environments as well as work itself. Venus also influences your appearance and how you feel about yourself. Transits of Venus through the Houses on your chart will bring a soft touch and desire to improve these areas in much the same manner as its placement natally.
As the second planet from the Sun, Venus' orbit lies between Earth and Mercury. It will thus always appear relatively close to the Sun and is often seen as what we identify as the morning or evening star. If you look at Venus with a telescope or binoculars frequently you'll see that is has phases similar to the Moon. It's often the brightest object in the sky short of the Sun and Moon, particularly when it's at maximum elongation. At that time, when it's extremely bright, it gets reported occasionally as a UFO!
Venus signifies the woman in a relationship while the Moon signifies the mother or wife when a couple marries. Conversely, Mars represents the man in a relationship and the father or husband in a family. Venus' placement in a man's chart will indicate the Sign or Ascendant of the type of woman he's attracted to, whether or not his Sign is compatible with it. Mars will yield similar information on a woman's chart.
Venus in the different Houses can provide the following influences. Aspects with other planets, either natal or transiting, will also have an effect, as always. The Sign of the Natural Houses is included since the effect will be similar.
1st House/Aries: Venus on the Ascendant will give the native a classic beauty that others will be drawn to and find very attractive. This will be permanent if this occurs in your Natal chart and transient if on your Progressed chart or from the Transits. If present in the 1st House generally it will have a similar though less dramatic effect. Those with this placement are aware of their appearance and maintain it well, according to the actual Sign involved.
2nd House/Taurus: As Taurus' ruling planet, placement here will be strong. The person will be attracted to beauty and items of high quality. They like soft, comfortable clothing and will manage their money and finances well. There may also be a tendency to consider loved ones as belongings.
3rd House/Gemini: Venus in the 3rd House will provide a general consideration of others that makes them very sympathetic listeners. Their decisions will be made with an awareness of their affect on others and they'll want to preserve relationships.

They are also likely to be fond of animals and may be inclined to take in strays of all kinds or volunteer at animals shelters.

Others will be drawn to them, which bodes well for those in a business that depends upon patronage.
8th House/Scorpio: Those with this placement are likely to have a tremendous amount of charisma and be especially intense emotionally.

12th House/Pisces: There may be a tendency to be shy and inhibited about love relationships and possibly fantasize about them more than they actually participate. Religious faith may become a replacement for romance or solace found in eating or drinking to excess. A creative interest, particularly one that produces a tangible result such as painting is a good outlet. There is also a tendency to attach extreme sentimental value to any possessions with special meaning.
