Too many sexual urges

Ok, i`m m/27 used to be a chef working all day to late nights, but then I changed careers to become a webmaster so I work from home abit. The problem I am having is way to many sexual urges and I need a way to slow it down. My friends tell me its a blessing, but to me its hell. Hear is my routine : I wake up at 5:00 a.m. with my wife, then I make love to her for about 20min . Then she goes to work around 6:00a.m. and I take a shower and work on the net during the day. (this is where it gets bad) from 7:00 am to 5:00pm (when my wife gets home) I masturbate 5 to 6 times. Then on top of that I make love to her after she gets home one or two more times the same night anywhere from 30 mins to 60 mins.(about 10p.m.) Then after saying goodnight I go back to the computer to try to finish the work I did not get done during the day and by the time I go to bed (around 1:00~2:00 a.m.) I may have masturbated 2 more times.As you may figure weekends are bad as well as she is home during the day, so every urge gets taken in by her. Don`t get me wrong, its not just mindless sex. I start out making her feel good b4 I start anything. But too much is just too MUCH.
I`m afraid if this goes on I may lose my loved one over time. This also is really affecting my work in a very negative way as I cant concentrate on work when I have these urges. My wife has expressed many times that this makes it very hard for her work as she has gone into work tired many times. This Is NOT what I want for my life, I want to stay with my wife and excel in my career. I need A healthy and safe way to suppress these urges.
Don`t get me wrong I love sex but not this much, one time a day is more than enough for me and my wife.
Also I am going to schedule an appointment Monday with my doctor to see what he says, I just wanted some feedback b4 then , Thanks everyone.
