I can't see two INFPs together in general. Unless there is something to pull one out of each other (damn...that sentence didn't even make sense, lol). I've dated a few INFPs. One INFP I dated had no interest even friendship wise in another INFP we know. She said the other INFPs art was "strange" and did not seem to care for it. Actually, my INFP roommate/friend and the last INFP I dated butted heads and did not like one another.
And I think especially if you are an INFP (perhaps introvert in general?) who feels you have issues with awkwardness and being too introverted, you are not going to want to attach yourself (or have the persistence) to try to date another awkward very introverted person.
If you have no such issues, I think the field would be more open for you to date another INFP and other introverts in general. Not saying that all introverts or INFP are awkward, just speaking to how a person's own hang ups or concerns really affects their attraction and willingness to engage with others.
I know two INFPs (they both tested as INFP on online tests, not sure if results were accurate though) who are fabulous friends but they are also both highly artistic and share a lot of interests. One is also clearly more outspoken and temperamental than the other.
I've also heard eccentric people call other people "weird" in a negative way. Since INFPs are a type that's highly likely to be considered "eccentric"...
From my personal INFP pool it seems INFPs are attracted to those that are more extroverted/socially skilled then them and/or those they find more intelligent.
This is somewhat similar with INTPs - I don't think INTPs are necessarily drawn to other INTPs for dating or friendship. At all. Types that are more likely to be drawn to each other for friendship or dating include ENFPs to other ENFPs.
