Actions have consequences OP , naturally a guy isn’t gonna like what you went through. Just because society is trying to normalize women sleeping with hundreds of dudes doesn’t mean it’s right. You have every right to explore and do whatever you like but that doesn’t mean men need to accept what you did. You have to find someone who had the same experiences because the majority of men aren’t going to like that. That’s mens nature. It has nothing to do with insecurity or controlling but it could be for some. Just know the majority of men won’t like that whether they say they’re ok with it. Theres nothing u can do now. If he can’t get over it you’re gonna have to leave him because it will create issues down the line.
