My husband says my rape story isn't rape. Can I have someone else's opinion please?

I was 15 and he was 19. The first time we had sex was because he heard me talking to one of my friends about losing my virginity. He said he didn't like virgins because "they are dead ****s." So, of course feeling I had to prove myself and to make sure I was doing it right I had sex with him. And he kept "letting" me practice on him. Even though I was dating his friend and he was dating mine, he was willing to help me out.
Anyways, I had sex with him about 20 times or so in a month (at 15 that's quite a bit). The day of the rape (?) I had just gotten back together with his friend and the day before he told me I was his "object of lust" but he didn't love me like he loved his girlfriend. But we were still hanging out and when he dragged me to our spot I told him I didn't want to have sex. After his pleading I conceded to making out and touching, but suddenly he was going to far. I said stop and no and tried to push him away, until finally I gave up. I waited for him to finish and then left the room.

When he finally came out he was sooo upset. He kept saying over and over I can't believe I raped you. So, me being as worthless as I am, told him just because I said no didn't mean it was rape. I told him he didn't rape me and everything was okay. Later, of course, it bothered me. How could it not? I mean it wasn't violent or a stranger, but still... It bothers me. Should it, though? I mean, is my husband right? Is this not really rape?
