Rob, there are many many ways in which you can blow off steam. Go for a run, go for a drink etc. etc. I don't think you and your team mates sleeping with and passing around a human being is really an acceptable, morally or anything, way of doing this. As kerry said - there are issues with STDs which could be passed on to your wife and any unborn children. I really cannot comprehend how any decent human being would think that doing this is acceptable, or desirable, or just a way to blow off steam?
I know for certain that visits to lapdancing clubs is very common in the City. I know someone who's female and in sales for a top tier bank, and very often has to take clients to strip clubs etc., and hates it. Although for most large companies it is completely against the expenses policy to do this, the clubs themselves come up as "Bob's steak house" or such on reciepts, rather than "Bob's sleazy stripjoint".
