I've found that the females are the only ones that ever go on about how funny, lovely and nice the flight crew are and it's quite amusing hearing the female cabin crew say, 'You should definitely visit the flight deck because they're such nice guys and are so funny!'
As soon as another male enters the flight deck, there is generally silence and a lot of effort to start and maintain a conversation. This could be due to the amount of sausages in a confined space but you'll mostly hear something along the lines of, 'Gee, what I'd give to get into that flightie!'
Of course there are ones that are happy to strike up a conversation with anybody, which are generally far and few between. Then there are those mentioned above, the ones with stories that end with the same punchline, 'What happens on an overnight, stay on an overnight.'
You can't really blame these guys as they're stuck in a confined space with other males for hours on end and I certainly don't envy that aspect of their job. However, I'm sure there are still many that are happily married and faithful to their loved ones.
