No, but it helps. For me, the person just has to be attractive irrespective of how I feel about them. The emotions usually makes the sensation feel better for me though. That is a double edged sword, however. I might get too excited if I feel strongly about the person. On the other hand, if it's just attraction then it's just pure domination without worrying about skeeting too fast.
It also depends on the kind of girl I'm interacting with. I tend to get excited from kissing and foreplay in general, but I tend to avoid kissing promiscuous girls (for obvious reasons), so it may dampen my enthusiasm for coitus.
For me, love making =/= fucking ... they're both sex, but the latter doesn't require emotions in my view.
