Although most stag weekends don't have much interaction between genders, it does happen, and it needs to be watched for, especially as company policies are still in effect. Some basic protections need to be observed.

If stag weekends were just boring affairs, then no one would go on them. But...they are usually far from civilization, with some alcohol (even if the planners don't bring any and place restrictions on it, it still mysteriously shows up), and something great did happen that day if everything went well. Throw two genders into the situation, and you know something is going to happen; it's just a matter of time. If it doesn't happen to you, it will happen to someone. And it doesn't take weeks to happen, but just minutes.

The basic protection that needs to be observed is that of mental protection. Harassment still applies, and can be still be prosecuted against the guilty party. That should be in the forefront of your mind, and you shouldn't forget it. At the same time, if you do approach someone make sure that you don't approach someone under your direct command, and that even then it can't be perceived as a threat against their employment or career path. Legally, abstinence really is the best option.

Also, be very aware of the person's marital status. Some jurisdictions do punish adultery, especially if it is a direct cause of divorce. This question gives some validity to the office gossip's position; check with him or her first before seriously approaching someone. You don't want to be on the receiving end of a jealous boyfriend, and jealous girlfriends can be as deadly. Look upon any kind of affection as you would a contract; try to avoid hidden clauses. They can be not only be inconvenient, but potentially harmful as well.

If something does happen, be prepared: Always carry a well-wrapped condom in your wallet. If it's ribbed or lubricated, fine, but it just needs to do its job. Latex is best; substitutions should be seriously debated.

Almost as potentially interesting as a midnight rendezvous can be, the morning after should be avoided. Two people leaving the same tent may be subject to scandal, even if they leave at different times. The best way to avoid this is to meet quickly, and leave quicker. Try to exercise some discretion in this, as a scandal is the only thing that travels faster than light. If possible, set up a wingman to help you get out of the situation with little observation of your personal movements; the wingman should not only be someone you trust, but also someone who is aware of the seriousness of the situation, and can actually help keep lookout.

By observing these basic precautions, the stag weekends can be fun, and hopefully be filled more with memories than sad reminders. Remember that you are watched, even when everyone is relaxed, and that your judgment is always being questioned, and a great stag weekend won't wreck your career.
