Responding to "Bises"/ "gros bisous"
How are men suppose to respond to "bises"/"gros bisous" in correspondances and texts or chat? "Bises," as well as "coucou," seems girlish. Is this the case? Is writing "bises" and saying coucou" more of a habit among women than men?
If someone writes "bises," am I (a grown man) supposed to reply in the same manner.
