Can't stop playing with yourself, spanking the monkey!!

I'm not sure if I have a problem or this is normal or what to think. I'm a 36 year old married male with two kids (2 & 6) and I spank the monkey at least 2-3 times a day, 5-7 days a week. I have sex 2-3 times a month, which are usually long satisfying sessions. Sometimes during the day I get so excited I have to go "relieve" myself. I'm not sure if this is an addiction or I just have a high sex drive. Can someone please comment to give me some advice.
Thanks:)
