Another indicator of his basic selfishness. That to me seems like the main problem in the marriage - aside from his obvious personal problems like drinking/drugging... although one could say that makes someone even more selfish in itself. The main problems all trace back to his focus being on himself. What does he ask himself regarding 'how can I make Gretchen happy'? 30 seconds sure ain't it...30 seconds isn't worth taking your clothes off for.
