Is it normal to want to have sex all the time?

I'm a 20 yr old girl and I crave and want to have sex all the time. I'm horny especially in the morning and in the afternoon. I feel that this is strange because the intensity of horniness that i've been feeling lately is abnormal. Lately it almost aches if I leave it alone or don't pleasure my self. I also don't sleep around and have no desire to sleep with strangers or guys that I'm just starting to get to know. I have two fuck buddies/friends with benefits that I have known for years but I can't see them when I want or frequently. Am I at my sexual peak or should I go see a profesional about this situation?
