I worked with a guy Dave, (straight) who was so laid back and unflappable that I thought he was medicated. Nothing ever got him upset or anxious, just chill all the time.
One summer, the sales manager had a cook out at his home for all of us and we could use the pool. Dave went swimming in board shorts, and when he got out of the water they were stuck to him and you could see everything. Flaccid, it must have been at least 8 x 5.
No wonder nothing ever bothered him.
