Some anal lubricants contain a desensitizer to make the anal play more comfortable. Since the anal region is not self lubricating, anal lubricants are very helpful for making anal penetration more comfortable and more pleasurable. Anal sex should not hurt. If it hurts, somebody does it wrong. With enough lubricant and enough patience, it's possible to enjoy anal sex. However, some people may never like it. If your lover is one of those people, respect their views. Don't force the idea upon them!
