Regardless of what you think, you hold a position of power over your staff and you must respect that. , or is it just a shared interest in the type of work that you do?
I know I leave a great deal of my personal interests in the parking lot when I arrive to work.
There are many different perspectives and differences in the workplace. Someone people only want to work for your company for money making opportunities only, and will see this as a poor decision.
Otherwise try to tackle the whole not dating your subordinates lifestyle first, to at least look like you don't need to leverage your ownership/managerial position for dating.
Lastly, keep in mind that some people do come into companies with the open mindedness of dating their coworkers.
Ask yourself "how many people have I dated in my life? Since you are again dating, this indicated that at least, your success rate at finding a permanent partner are less than 10%. Adjust these statistics to your own personal experience.
How many of those relationships ended badly or turned ugly? Chances are, however you slice it, you are making a gamble and you do not have the edge.
