Should I be mad at my boyfriend?

I was talking to my boyfriend on the phone tonight. We are a new couple and don’t get to see each other right now except through face time because I go to college kind of far away from my hometown. I’m moving back home at the end of the month. anyways he tells me everything on the phone and tells me how much he likes me and swears he’ll never leave or hurt me. Some people probably roll their eyes at this but I can only go by his word and I trust him. We’ve talked about our exes before and he told me he dated a girl in high school and it was really toxic so they broke up. Today on the phone he told me that he met this girl at a party in high school and they dated for a while and he dated two girls in middle school. I kind of flipped on him because he never told me this before. He made it seem like that one ex was the only one. I asked him why he never told me this and he said he didn’t want to seem like a player and he sounded really bummed and worried over the phone all of a sudden. We’ve been talking for three months and a couple for two and he’s never told me this before. He told me he didn’t want me to be mad and it was all in the past and not a big deal and he was scared I would stop talking to him for it. I eventually let it go but he told me he would never lie to me about anything and would be open about everything and swore on the Bible. I really like him and he’s a good boyfriend but should Ik be mad at him for this?
