Admittedly I did the exact same thing as you, right down to the same quote.
Most male dominated fields of work behave like this - it's a reflection of subtle rules society that we're taught at a young age. We can try to patch it over but it might cut deeper than just culture, it maybe simply inherently biological the behavior of men around a single female.
