Seriously, I don't get how this is hard for folks. It's unbelievably simple. Be aware that you may have professional power over other people, and if you do, make an active effort not to flirt with them. Have the self-restraint not to mix an investment/supervisory relationship with romance or sex. Either it will feel coercive, or it's a conflict of interest waiting to happen.
Avoiding trying to sleep with your subordinates is not rocket surgery.
