I'm always wary of similar last letters (J + J, P + P). From what my ENTP friend in NY tells me, every time she dates another P, it always feels like nobody is willing to initiate anything. So in your case, it may end up being similar to the repeated scene from King of the Hill, where all the guys are just sitting in front of the fence saying "Yep... Mmhmm... Uhhuh".
I dated an ENFJ this year, and anything physical was awkward to the point of pain. The way I look at it is P's bring the playfulness, and J's bring the intensity. I think most of my better relationships have been with other P's.
I like sitting in front of the fence saying "Yep... Hmhmm... Uhhuh".
As for initiating stuff. I find that extroverts in general get me in plenty of trouble (and in the process, fun).
Also, the people I get along best with in life are XNXP's.
