Is it normal to have past relationships from middle school and high school?

I’m 24. My spouce and sons father of 5 years, is obsessed over my old boyfriends from years ago. I had 4 previous boyfriends who I thought was love with never were because let’s face it, I was young and childish to know any better on what love is, but it bothers him that I liked other guys before I met him. I never cheated on him, never did anything shady nothing. We just fight because I had boyfriends and because I didn’t lose my virginity to him. I regret even answering his questions about my past because I never imagined he would be the type to rub it in my face and give me shit over it. But I was honest because I thought it would make us close, knowing things about each other. Instead he calls me a slut and whore and the city whore. All because I had sex with only my 4 ex boyfriends. Unlike him, who was a party animal and got shit faced all his high school years and who definitely was not a virgin when he met me, I feel like he feels guilty about something going on with him that he feels the need to fight with me about high school boyfriends who can never make me feel the way my spouse does. I tell him I love him and he’ll ask me why? If You had your first love already.... and then he’ll bring up the fact that I had an MySpace account with my first boyfriend, which he knew about a week into being with me, and the account was made when I was 15 back when MySpace was the Facebook on my youthful years. The account was empty no photos no nothing, just my username which was my name and the name of my ex. Up until 3 months ago he decided to bring that up and since then will not let it go! He told me I had to figure a way out to delete that account or he would not marry me. I was able to contact MySpace and they removed the profile. But 3 months later, my past is always being brought up. He told me he feels crazy for thinking that way but it grosses him out. Yet he still has sex with me, but then will end up bringing up the past passively.

Am I a slut for having 4 boyfriends before my spouce? I met him when I was 18 going on 19 I’m 24 turning 25 and he’s 25. Does it make me a slut that I had 4 boyfriends making him the 5th? I regret opening up to him and wish I lied. Lesson learned I guess...
