Bf Gets Mad At Revealing Pics

My bf and I r 17 and 18. We’ve been together a year and a half. My bf hates when I post pics in a bathing suit. I personally don’t see it as a big deal. I’m a life guard so I sometimes post pics in my guard swim suit. He’s made comments abt it in the past and I’ve had to take down certain profile pics cause he thought it showed too much. Last night he was making comments abt how I don’t have respect for him and that I’m trying to impress other guys. Which im not. Im a teenager and I like posting cute bikini pics or whatever cause it makes my feed look good. I’m not trying to make him mad. My bf himself likes other girl half naked pics which I told him I didn’t like but yet he kept doing it. So I do what I want. Last night he even said “if u wanna post those pics then date someone else then.” He also said he thinks I might be bored w him and which is completely not true. I love him. Am I actually doing something wrong? Advice?
