masterbating in older age

I dont think that l would be overly worried about what you are doing, it is very normal to masterbate, even though you have a wife and are obviously having sex.

Try not to also worry about fantasing about who you are thinking about, this is very normal, everyone has fantasys, about all sorts of things. As long as you dont cross the line, be happy , masterbate and fantasise.

And dont be stressed, you are not hurting anyone

Masterbation is perfectly ok and healthy at any age in my opinion. It helps in many ways such as stress relief and more.

I'm not sure how "ok" it is to be thinking about the people you are thinking of but to each their own.

Be happy in life and use a lube :-)

There is nothing wrong with fantasising I do it all the time with friends and ex partners and famous people only you know who you think about so it's ok
