Is it normal i think about sex a lot after finishing a college semester?

I just finished a college semester a few days ago. Ever since then, I can't stop thinking about sex. Maybe it's because I am not as busy anymore? Actually, I have nothing else to do now that school ended. But I am becoming frustrated because of being horny I guess. Last night, I texted someone who happens to really care for me and he helped me cum through texting alone. Do I just really need sex nowadays?
