New to Sex

So I recently lost my virginity to my boyfriend. Initially, sex was painful but now things are going smooth. It’s been around 1.5 months now. The only thing I’m concerned is

1- He’s a bit rough at times. Bites too hard... thrusts too hard that it gets painful.... Is it normal?

2- He uses language such as “ Suck my cock Bitch” which I feel is derogatory. Am I missing out something?

3- The act is over when he cums. I haven’t had an orgasm once. I am becoming a little desperate now. What should I do?
