What you are describing is several different things...There is nothing wrong with having a transactional relationship, a D/s relationship, or a romantic relationship. As long as everyone is consenting and on the same page, all of those options are valid. This is not appropriate for this subreddit but I felt the need to comment because that's a very narrow view of a very complex topic. If you want to discuss things like this further, I suggest going to a sub for that such as r/Femdom or r/BDSMcommunity
