Which reminds me.....the modelling discussion board, to which I also belong, has a very interesting (and veeeeery looooong) thread about male models getting an erection while posing. I'd always thought that that was taboo (indeed, the word "taboo" is in the title of the thread), but apparently quite a few drawing groups request that of their male models on occasion. Interesting.....The models who were talking about this were saying that that can be the most difficult part of the pose to hold (as 'twere!) - as it requires some mental effort....!

For anyone who's interested, here's the link:
