There are a few things you can do to make sure your rice isn't overly sticky and clumpy. 1) Make sure to rinse the rice thoroughly before cooking, to remove excess starch. 2) Cook the rice in a little oil, to coat it, before adding the liquid. 2) Avoid stirring the rice while it is cooking. 3) Once the rice is cooked, fluff with a fork to separate the grains and release any excess steam.
