sex addiction??

So I'm kinda having worries that I have a slight sex addiction. I know I have quite a high sex drive and I think about sex quite a lot just randomly throughout the day, but recently I've realised the characteristics of it are similar to that of an addiction. If I decide I want sex I get really restless and distracted if I can't have it, I find it hard to focus on work and sometimes when I want sex and my boyfriend doesn't I find it really hard to accept it and move on I get really restless because I can't stop thinking about it even though I know it's not gonna happen. Anyone had anything similar? Is there anything I should worry about?
