It is definitely easier to want to be in a relationship with someone who is hot vs who is funny. So it's definitely easy to see how someone hot could get into many relationships, but making a relationship last requires personality. Looks are a surface feature that's something that everybody notices all the time, which is not something that you can sustain a relationship on. Personality is what draws people together. Things like common interest and the ability to make people laugh are what gets a relationship through the bad times and leads to good times.
