Always masturbating

So, ever since I got vibrator; I've been masturbating every night. (clitoral stimulation). Before I got the vibrator; I have never had any orgasm but now, I do everytime. Sometimes, I do it 2 or more times a day. Most times, I just do it once before I go to bed. I think I may be addicted to masturbation. Am I normal? Is this normal? Meanwhile, I am 27 and single (No BOYFRIEND OR LOVERS FOR OVER A YEAR NOW)
