Can/Should a single pastor do premarital and marriage counseling?

I have seen some stuff about marriage and relationships recently on this sub. This is a question I have had a number of times in my seminary classes. As I am single, and I plan on going into ministry, eventually, I will need to do some sort of counseling for marriage or pre-marriage. I have my own opinions on the matter, but I am interested in what other people have to say about it.
