In Europe most rooms have only 1 bed by default.
Probobly why my company, and most I know pay for 1 room per person for business trips. No company would expect people to share a bed (unless married) as the chances of being taken to court if something did happen would be much to high.
As for men thinking about sex every 4 seconds, that number seems to change alot. It is one of those things that everyone quotes, but no-one has seen the original study. Doing a search on google for "men think about sex" and "Seconds" returns answers from 3-11 seconds, and one saying 30% think about it less than once a day.
I did the same seach but changing Men to Woman. There was more consensous there. 6 of the top 10 agreed on once every 6 seconds.
