I can't give you personal experience with being in a relationship with an INFJ, and I'm not female anyway. However, I can once again bust out my MBTI relationship book again!
Amazon.com: Just Your Type: Create the Relationship You've Always Wanted Using the Secrets of Personality Type (9780316845694): Paul D. Tieger, Barbara Barron-Tieger: Books
It's neat, it takes all 16 types and talks about every possible pairing, naming the joys, frustrations, and things each type can do for one another.
In the joys section, it talks about how the two types are both kind, caring and gentle, making it easier for them to feel comfortable sharing their feelings. They also both have strong values and like a more predictable lifestyle, so they take each other's committments seriously and respect routines. In addition, ISFJ's are drawn to INFJ's creativity and originality, while INFJ's get security out of the devotion and dependability of the ISFJ.
In the frustrations section, it talks about how INFJ's can have problems with ISFJ's conformity and focus on tradition. INFJ's might find the ISFJ to be too cautious and slow to try new experiences. ISFJ's meanwhile, can feel hurt by INFJs' tendency to focus on tomorrow, feeling as though that means that the INFJ isn't satisfied with the way things currently are in the relationship. An ISFJ can also feel belittled if the an INFJ becomes impatient with them. The other problem is both types are sensitive and can easily get their feelings hurt, especially if something is misconstrued. So what can happen is that both types may bottle up emotion since they don't like confrontation, leading to big emotional outbursts.
It's interesting, another INFJ posted a thread about his problems with his ISFJ ex-girlfriend, and this next bit reminded me of that. It says that INFJ's are usually the ones to initiate the confrontation after noticing patterns, but when the confrontation does occur, it would be better if the INFJ stays on topic and doesn't bring in unrelated issues, and the ISFJ should not be too defensive or discouraged by the conflict.
Here's what it says INFJ's should do for ISFJ's:
-Appreciate all the tangible and thoughtful things your partner does to take care of you, your home, and your family.
-Participate in some of the physical activities you partner enjoys, especially those that get you out of the house and into the natural world.
-Be specific about your requests, concerns and complaints.
-Don't gloss over important steps or leave out key information. Carefully keep track of money.
-Try not to make or even suggest too many changes too quickly.
-Respect your partner's routines and honor the practices that bring him or her comfort.
Here's what it says ISFJ's should do for INFJ's:
-Try to articulate your thoughts and feelings rather than assuming your partner knows how and what you feel.
-Be patient with your partner's desire to uncover the hidden or subtle meanings of things.
-Focus on the positive, especially in everyday matters such as money and maintaining your home and possessions.
-Compliment your partner on his or her many fresh ideas, unique mode of expression, and ability to see the big picture.
-Be patient with your partner's sometimes vague or convoluted stories.
-Thank your partner for encouraging you to plan for the future.
I know you're not really in a relationship situation, but maybe this will help a little. But like Seeker said, type shouldn't dictate who's compatible or not, there's so much more to it than that. Type may play into things, but people are people.
