Relationships are not measured in quantity, but in quality. This boy may have had relationships before, but what were these relationships worth? How long did they last? If he has had multiple, I would say he is more UNLUCKY in relationships that you are. Relationships are about finding ONE person who completes or betters you. I would rather have no relationship at all than a bunch that meant nothing. Why waste time on something insignificant?
Of course, you could always count these as “practice relationships” (relationships that get you ready for a real relationship) where, although there is feeling, there is no true passion or emotion between the two people dating.
Don’t rush into a relationship just because you want to be in one, or because someone else has had more or has been in one for longer. Relationships are not a competition. Wait for someone who makes you feel like you two belong together. Don’t fall in love with love.
