Young age many men

BB
Im 16 and had 12-15 sex partners. My boyfriend is 20 we have been together 9 months & sexually active ( yes my parents are aware of , not to okay with it but allows me to make my own decisions) but anyways my past with number of people have just came up and he cant get over it so we broke up . I love him i dont want to lose him i know he loves me but hes the stubborn type and i dont know what to do. Please dont judge i am aware that it is wrong and nasty . Besides him iv only has unprotected sex once.
