Men use ne vs women use ne

I can't remember if men use the particle ne as much as women, Do men use ne? like "そうですね". A person who was teaching me Japanese told me that men do not say またね, it's for women and men use またな. So do men use ね?

Yes, also men use ね, it sounds more softly and polite than ね.
またな or そうだな is rough and used among friends only.
Mannish women like Kusanagi Motoko use な.

Sorry.(x_x;)
ね sounds more softly and polite than な.
Also men commonly use it.

I live in Kansai region. In Kansai, men rarely uses "ne" because it's feminine. Maybe the person who teaches you is from Kansai. But sometimes men in Kansai also uses "ne". In politely expression like そうですね, they use "ne", I think.

Fifty years ago I knew a girl (about sixteen) who used "na" where many would say "ne." Other people in town seemed to be startled by this. Perhaps it is more common and less surprising now. (I know this is the reverse of what you asked, but it was what I was put in mind of.)

mans "ne" ,,,,,i fell like kids or very friendly but not adlut

womans "ne" is useful and i hear many time

We should keep in mind that the original question is asking about keigo and not "matane/na" which is totally casual.

As far as "soudesune" is concerned, no person, men or women, says "soudesuna" unless (s)he is talking in a dialect or unless he is quite an older male. I think the OP has it mixed up with casual expressions.

I can't really think of a keigo expression that can end with a -na and not sound older than 60.
