I want 8" NBPEL. I have a large fat pad, though, (1.5-2"), which would require a ridiculous 9.5-10" BPEL. I'm in the process of getting fit, so hopefully my fat pad will be down to 0.5-1" some day; accordingly, for the sake of the poll, I'll say 8.5-8.99" BPEL. (Currently 8" BPEL.)
My wife has the final say (she's the one having sex with me, so her opinion matters) and she agreed to 6.5"BPEL x 5.5"EG as being the maximum that I'm allowed to do. She isn't a size queen and one of her toys (soft, multi layer and creepy realistic dildo) is that size and caution must be used using it. I think that's fair and everyone is happy.
