I go thru phases too. I'm in my 40s now, and have been masturbating since I was about 10 or 11. LOL. In those teen years, used to do it morning and night.
In my 20s I would sometimes spend the whole weekend!

Married now for 20 years, and have gone thru phases of only doing it once a month, what with all the regular sex I'm getting as desired.

But in the last few months, I've been a lot hornier (!) and have done it at work (lucky me in a quiet office with a lock, which office is well out of the way) as well as at home. I've only gotten comfortable doing it in front of my husband in recent weeks, and it turns him on.
