I think a man needs to display both masculine and feminine traits to his woman to make that deep long-lasting connection, the tricky thing being to have the EQ (emotional quotient) to know when to bring out the SNAG (remember him?) and when to be a proper bloke.
I am in touch with my feminine side -- in fact, I touch it every chance I get -- and am not afraid to show it to the right ladies. To other blokes, not so much.
