What does the なる and the と mean in this sentence?

> でも男のことに **なると** 、どうにも弱いとこがあってさ…

From what I have learnt so far:

  * と can mean "and", eg. 私は水とジュースを飲んだ

  * と can be used to imply an inevitable outcome, eg. 六時になる **と** 、太陽が見える

  * と can be used to quote a thought or something that somebody said, eg. 「強くなりたい」 **と** いったでしょう？

But it seems that the と in this sentence doesn't fit any of these usages.

As for the なる, it usually means "to become", right? But in this case, it says
男のことになる. 男のこと means "about guys", and that is not something you can
"become"...

What does the なる and the と mean in this sentence
Xになると and Xとなると are synonymous set phrases that mean "when it comes to X..."
or "as for X..." They have nothing to do with something becoming something
else.

> でも男のことに **なると** 、どうにも弱いとこがあってさ…

The と is a conjunctive particle (接続助詞) meaning "When" or "If". It's the と in
your second example:

> と can be used to imply an inevitable outcome, eg. 六時になる **と** 、太陽が見える

> that is not something you can "become"...

The subject of the なる is not the speaker, but more like "things" or "topic".

As the other poster says, 「～（こと）となると、」 or 「～（こと）になると、」 is a set phrase that
means "When it comes to~~" "Speaking of~~".

I would break it down to...

男のこと - matters/issues about men  
になる - (it/things/situation/topic) becomes  
と - when
