This may be an unpopular opinion, but I believe anyone can become addicted to anything given the right circumstances. If, even when having regular sex, the thought of more is dominating your thoughts and actions so much that it is interfering with your ability to function (work, maintain your home etc.), then perhaps you have an addiction. Most importantly you must look at whether or not the actions you're undertaking as a result are making you unhappy.
That being said wanting to have sex on a regular basis is perfectly normal, and being driven to seek out sex is also normal. As with all things, balance is key.
