I only have 1 PP, but I have written to 4. The other 3 did respond, but for one reason, or another, we didn't continue.
But, I have always had good luck in getting responses. And there are those who have not.
Perhaps one advantage is that I write to more mature ladies and I don't think that they get as much mail as the young and the beautiful inmates.
I hope that you are able to find a very nice friend. :-)
Live simply, love generously, care deeply, speak kindly.
