Guys, How would you react if a woman beat you in armwrestling?

Today I met a woman who was 6'7 at a social gathering. She was a fairly eccentric lady from Denmark. She challenged me to an arm wrestle and at 3 inches taller and 40 lbs heavier and after 90 seconds of intense fighting she beat me on both my arms. I feel so embarrassed as I've never lost an arm wrestle. How would you react?
