Typically it goes like this, regardless of where I am or who I am talking to, nine times out of ten it will go something like this.
(I'll be sitting somewhere having a drink, or at a party, or an event, or anywhere where men and women congregate).

Before you slam me for lack of social distancing, this happened in my apartment with a neighbour, I am not 'out and about' yet. The specific situation was so typical of what happens, it prompted me to post.

In this specific situation, I was in the pool at my small apartment building.
I was at the far end of the pool, where there are bar stools in the water, at the perfect height for me to do various arm / shoulder etc exercises.
I've been doing them since I moved here in January and they are working, my arms are tightening up slowly but surely. (I've lost a lot of weight recently and need to tone up various parts).

Anyway that's got nothing to do with the story (I just wanted to brag about my weight loss LOL)

So there I am in the pool, doing exercises, having a swim, winding down after a long day etc etc.

My neighbour yells out - "Did I see you doing arm exercises over there?"
I responded that yes, that is what he saw.
He yells out - ''Come over here, I will show you how to do them properly"
I said - ''What I am doing is working for me, thank you"
He said - ''No no, doing them in the water isn't as effective, come here so I can show you."
I said - a little bit louder "No, really, I am very happy with what I'm doing."
He said - let me help you!
I said - ''How about when I need your help, I'll ask for it."
He got really aggro about it so I got out the pool.

I walked into my apartment to him muttering things about feminist bitch etc etc.

I'll often be minding my own business and all of a sudden I'm defending the fact that I don't want to take advice I didn't ask for.
Do men do this to each other as well?

Some people do, some people don’t Rozzie. It’s not a problem unique to interfering men. There are plenty of women who offer unsolicited advice too.

Middle aged water aerobics triggers deep seated primeval rage in men because...........Middle. Aged. Water. Aerobics!!

I had a man say something to me about the form of my bicep curls, my elbow was sneaking out a bit. He was right about the elbow, but it is true that he was being a typical man in informing me. I changed to a new gym.

Same reason we can't ask for directions.

tl;dr
is it the same reason women create imaginary problems?

edit:
yes men do this to each other too
in fact i think many feminist complaints actually result
from when men treat them as they would other men

have a look at accounts by trans-men
'male privilege' comes with a heavy price
