^^ Wow, that coming from an ENFJ dude! I'm surprised! But maybe that's the difference between ENFJ/ENFP? Do you feel obligated to manage or 'take care' of the emotional health of those you date? Or in other words, make sure they are feeling a-okay and acting appropriate?
Do you really think 'F' means over-emotional? Now I'm curious about the women you've dated.
Or maybe there's only room for on NF in your relationships.

In answer to the OP --
Finding an ENFP female is similar to finding an ENTP female -- sometimes -- as far as venues are concerned:
1) I take a lot of random classes that's usually populated by couples, straight women, and folks who are much older -- basically they aren't 'singles' kind of classes so if you found your way into one you'd have really good odds!
2) At the club. It's the Extraversion + Fi.
3) Volunteering, particularly counseling or outreach, or in a group related to psychology... or counseling... or puppies... or babies...
4) Anything else that pops up under 'recommended jobs' for XNFXs -- teacher, journalist, therapist, actor, etc.
Umm...between those 4 suggestions you should be able to sift through and find your NF women in there somewhere.
