Be 100% masculine at all times.
Always be dominant and in control. Take charge - be the leader - the boss. Do
everything with authority. Instruct - never ask. Never seek approval.
Show that you got limited respect for her and that you are not subdued by
social norms/rules (scream in her ear, make noise, laugh and sing loudly, pull
her hair, pinch her ass, grab her and bite her neck, shout about farting and
ass fucking, laugh and admit you are a jerk etc)
Never show a soft emotional side. Don't show interest in her thoughts and
emotions.
