Hmmm. When does it stop being NRE/NRC and start being ORE?
I would agree that the OMG I WANT YOUR BODY RIGHT NOW wore off about a year or so in for every relationship I have ever had.
But, with my two current loves (15 & 20 yrs) I experience the giggly, touchy feely OMG YOU ARE SO AMAZING sensations regularly and my hormones create a NRE-like cascade of sexual craziness every month for aboit ten days when I would HAPPILY accost both of them day in and day out.
