On the opposite side of this, if a woman holds the door for you, don’t take it as a comment on your masculinity.

I always hold doors for people if I’m ahead of them.
I almost always get a polite “Thank you” from women, I can only think of 2 times when they haven’t.
I’d say, maybe 75% of men thank me.
I’m not saying it’s definitely because they feel like it’s emasculating to have the door held open for them. But I believe in some cases it may be a factor.
In no other interactions have I noticed such a large gap in politeness between the genders.

One particularly noticeable incident:

One man stopped dead, said “I don’t let women open doors for me” grabbed the handle off me, shut the door then reopened it himself!
He then literally jogged past me to the next door to open it for me.
I’m sure, in his mind, he was being chivalrous or something but it just seemed like one of the most childish thing I’d ever witnessed.
