Sticky pasta

Hehe, it's like the ten commandments of pasta

Good answer. 

A number of good suggestions already; I'd underline 1) that you might well be cooking it too much; and 2) you need to add something such as olive oil or the sauce after straining.  To elaborate on the 2nd point, timing is key.  When I make pasta, I time it to make sure the sauce is ready first, that can be kept warm on low heat with no harm done, then added as soon as the pasta is ready.

put olive oil in the water while you cook the pasta run cold water over it also add salt to the water so the pasta doesnt stick together remeber to put the salt in after the water starts to boil and before you put the pasta in the water
