My fiancée and I had a long-distance thing going. She was in Pennsylvania; I was in Alaska.
We'd spend incredible amounts of time writing to each other, or on the phone to each other.
Somehow, it often happened that when one of us called the other, we were both just finished bathing. So we came to have regular towel-and-wet-hair conversations.
Her mom wasn't very thrilled with me, since I was the Older Woman. (Well, OK, she was 14. And I was 15.)
