To the late 30s woman who wrote the item named above - I fully agree!
Over the years I've had the pleasure - and honor - of sharing masturbation with a few women in my life, two person to person, a couple more via the phone and internet, and when I say pleasure and honor, believe me, I mean it. No need to 'make things up,' and frankly, 'made up' would pale compared to the reality of the experiences. The ladies I've known have been all woman, with a mind and feelings and needs and desires as strong as mine, and having shared such moments with them is among my fondest memories.
I caught my ex-wife doing herself one day, and after talking about it afterwards, masturbation became a normal part of our overall relationship - to me, not only was it fascinating, but the fact that she would so willing share such a personal thing with me made me feel very special, and more than willing to share as much with her in return. The same thing happened with a girlfriend some years afterwards (see my previous items, Phone Sex and Phone Sex - Followup), and in each case, I felt that their masturbation and sharing such with me showed how complete they were as women and as persons. Too, not once did I feel threatened because they were taking care of their own needs from time to time just as I was - why should I? If it's normal for men to masturbate, why wouldn't it be normal for women too also?
Yes, women are real, yes, they are sexual, yes, they have feelings and needs just like men do, and men, believe me, you're better off to recognize that and accept women as the equals they are.
And I'll concur with the comment: Keep doing yourself and enjoying yourself!
