Is it normal: that i don't miss sex?

Well, I had sex about four months ago and it was really good, but me and that guy stopped talking because he is really annoying and not good for anything else. I had a really bad sex addiction for years before that and I am only 20 so my hormones are still raging.I get horny, but I don't care to have sex. I don't miss it at all. Is that normal?
