How personality is related to sexuality

This new, large meta-analysis of 761 effects sizes with a sample of over 400k people looks at the relationship between personality traits sand sexuality. 

People who score high on neuroticism (the tendency to experience negative emotions like anxiety) are less sexually satisfied (r = .18) and have more symptoms of sexual dysfunction (r = .16). 

Extraverts engage in more sexual activity (r = .17) and risky sexual behavior (r = .18) and have less sexual dysfunction (r = −.17). 

People who are open to experience are more likely to be homosexual (r = .16) and to have liberal attitudes toward sex (r = .19). 

Highly agreeable and conscientious (i.e., self-disciplined) people are less sexually aggressive (r = −.20; r = −.14) and are less like to be unfaithful (r+ = .18; r+ = .17). 

So, if you're looking for a trustworthy partner who enjoys sex, your best bet is to find a person who is even-keeled, cooperative, and diligent. 

By the way, these traits are highly influenced by genes, so don't assume you can change someone into a desirable partner. A major theme among people who take genes seriously is, what you see is what you get (WYSIWYG).
