Lube for anal

Hello. So me and my boyfriend are planning to do anal for the first time and i was looking at what kind of lubes i can get and started getting confused on which one is best for anal. As i started looking at durex lube as they are easy to get at any drug stores but then there was gels and jelly which i don’t understand the difference between. So my question is what is the difference between gel and jelly lube and what is the best durex lube to get for anal. Thank you 😊
