WE know how Matthew McConaughey learned to be so open about his sex life - from his mom, Kay McConaughey. In Kay's new book, "I Amaze Myself," she talks about some pretty personal stuff, including how her husband, Matthew's father, died while she was having sex with him. "On Monday mornings, he and I often said goodbye by making love," Kay, 78, told Us magazine. "One day, all of a sudden, it just happened. I knew that something was wrong, because I didn't hear anything from him. Just nothing. But it was just the best way to go!"
