Venus in 7th house. 

So, lets see what Venus can do in 7th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent --

Venus is beauty, desire and love, liquid money, Venus is beauty, desire and love. Venus is the main significator of marriage. Venus represents girlfriend or wife for a man. Venus is the significator of all relations, may it be husband-wife or mother-daughter. Philosophically speaking, Venus is also the cause of all the sufferings in our life. How? Because Venus represents our desires and we get pain and suffering in our life only when our desires are not fulfilled.

7th house is house of market place, other people (masses), business partnerships, agreements, marriage, spouse, marital happiness etc.

So, planet of relations is coming into the house of relations. This person can be all about relationship. Spouse will bring beauty, convenience and love into relation. These people like to make agreements between the parties and earn from that as Venus is wealth. So, they become good attorneys/diplomats and bring agreements to take place. These people find their happiness into relations. They are very good in keeping and maintaining relationship. They should approach relations like a service to other person, then relation can be good. 

From 7th house, Venus aspects the 1st house of personality and self. Here, Venus blesses the person with a pleasant and beautiful personality.
