So this is kind of odd but I get too heated too often. What should I do?

I am disgusted to even ask it but I work hard and am a busy person. I am trying to stay celibate but its real hard. I'll be running and I am . I could be sleep and am needing cold showers or pillows. I'm 21 so I know its not menopause. I am too busy for a boyfriend......and not willing to gve it up...is this even natural?
