I am an older lady of 65 years but still masturbate daily. I really love to masturbate and I badly need to orgasm every day (I mean regularily every night in my bed).
I started to masturbate when I was fourteen and then I continued to masturbate my entire life long. Especially when I was of the age between 30 and 45 I had the highest masturbation frequency, up to four times a day.
I would be pleased to hear (or to read) if there are other older women who still masturbate aged over 60.
