Who Has A Dirtier Mind?

I have always wondered who has a dirtier mind, a person in a relationship or a person not in a relationship.  I would say a person that's in a relationship because if you are in a relationship then you have access to various love making choices so getting kinky with your lover is always on your mind.  Whereas, if you were single then your mind isn't on your lover's crotch because you don't have one but on other things to occupy your mind but that doesn't mean that you don't think about getting down and dirty with someone but just not as much.  What are your thoughts?
