To love means to open ourselves to the negative as well as the positive - to grief, sorrow, and disappointment as well as to joy, fulfillment, and an intensity of consciousness we did not know was possible before." -- Rollo May
ENTP's goals for their intimate relationships are similar to their other personal goals: improvement and growth. They constantly ask themselves questions such as: How can the relationship be improved? Where is the relationship headed? Am I growing in the relationship? They are likely to enthusiastically embrace new ideas and projects for themselves and their mates which they feel will propel them along their goal for growth and knowledge discovery. The ENTP's general enthusiasiam and good intentions are usually quite positive and healthful in a relationship.
A problem area for ENTP's is their tendency to not follow through on their schemes. This can be frustrating to their mates. It may also create a "boy who called wolf" syndrome in their relationships, with their partner never believing that the ENTP will actually do what they say they'll do.
Another potential problem area is the ENTP's general tendency towards "wildness" and willingness to take risks. They may lead the family into uncomfortable financial situations, which can be quite stressful on intimate relationships.
Sexually, the ENTP is enthusiastic and interested in positive, constant growth for both partners. They're likely to be very attentive, involved, and questioning. They enjoy spontaneity rather than fixed schedules, and fully embrace new ideas and adventures. They're likely to approach intimacy as more of a physical act which conveys affection, rather than as an opportunity to explicitly express affection.
In general, ENTP's childlike enthusiasm and genuine interest in the health and direction of the relationship makes them willing and able to promote healthy, growing relationships with their significant others. They need to watch out for their tendency to be unaware of what others are feeling, and to inadvertantly neglect their relationships when faced with exciting possibilities that are external to their personal life.
Although two well-developed individuals of any type can enjoy a healthy relationship, ENTP's natural partner is the INFJ, or the INTJ. The ENTP's dominant function of Extraverted Intuition is best matched with a personality that is dominated by Introverted Intuition. How did we arrive at this?
