Masculinity is founded on the renunciation of femininity. Boys have to emphasize their difference from their female mothers as they simultaneously attempt to separate from them. Thus, masculinity is based on negating femininity which makes it inherently brittle and unstable. Boys further learn to devalue femininity in order to reinforce their sense of separateness and difference. Normal love and intimacy threatens these defenses. Boys, and later men, use objectification and emotional withdrawal in their attempts to feel safe.
