Lovey dovey "phase"?

I was talking about my boyfriend to a coworker, and she told me she misses the first little lovey dovey phase of new relationships... it made me sad that maybe one day my SO and I will stop being all cute and loved up?

Is anyone in a long term relationship and still in the lovey dovey stage?? Cause I don't ever want to stop feeling butterflies around him and wanting to kiss him and hug him all the time, I hope he doesn't either
