Do you agree that I got hurt for no reason?

So this happened a while ago with my ex, but I saw a post that made me think of it and I would love your guys opinions. My last ex was the first guy I ever had sex with. He had mentioned previously that he never was too interested in sex(as he was with other things)so he put no pressure on me which was nice. And when it finally happened naturally, he was having a bit of trouble finishing. Which at first I didn't know, I just thought that that's how it works or maybe it was something I was doing wrong. So I offered to finish him, he said yes and that was the end of it. I didn't think it was a big deal. But then he apparently went to his girl best friend(whom I've never met) and told her all about it because he was apparently upset with the situation. To make matters worse, when he told this girl, I didn't know, all(and I mean all) the details about my first time, she told all of her roommates.
When he told me I was really hurt for multiple reasons 1)I don't know this woman and now she knows all about my first time 2)that he was my first which supposedly meant a lot to him, yet he was not comfy enough to discuss his concerns of OUR sexual experience with me. 3) he said nothing &whist watched as she told all her friends. 
He argued that he didn't think it was a big deal bc she's more experienced so he always goes to her for advice. And there was no point in getting mad at her for telling bc he didn't want to start an argument. He basically then told me I was hurt for no reason and he did nothing wrong. I'm still annoyed by it even though it's been months but common I'm sure  I'm not the only one who would have got annoyed:/
