How many romantic interests do your Sims usually have?

Every Sim is different but in general, I love to give my simmies options and have them date a little bit. Usually, there will be about 3 love interests for them to choose from before I finally have my sim settle on one. But I have sims who have only been with their high school sweethearts and sims who used the Serial Romantic aspiration to be in faux-poly relationships.
