Advice please :((

Hi, I’m 16 years old and have been dating my boyfriend since September. My boyfriend has recently asked me if I wanted to try making out with tongue. Honestly I don’t feel ready to do that sort of thing so I shut him down. He said okay but keeps asking. I repeatedly told him no and that I don’t feel comfortable doing that. He got angry at me and asked why I can’t “just try to see if I would like it” and that we have been dating for a long time and “nothing has changed.” So should I just do it to make him happy?
