Sex complications

Hey ladies so just asking for advice to see what everyone else would do. Your boyfriend wants to spice things up during sex but he brings up things like cuming on your face and asking you to beg for it but you aren’t comfortable with that stuff. Do you still do it because it’s what makes him happy? Or do you not do it because you aren’t comfortable?

Because I’m okay with having typical sex. I don’t like when things get crazy but I wonder if I’m being unfair to him by not giving him what he wants during sex.
