How do women like men to shave?

There is no specific answer to this since it varies per woman, and a lesser degree per man. Many woman prefer men who are clean shaven. Other women like some facial hair since it showcases masculinity, but short and neatly trimmed. Other women like a full beard and mustache.

So the best way to find out is to ask your girlfriend, spouse, or women of the type you are interested in (even if they specifically are not into you).
