Sex life issues..

So me and my S/O have been together 2.5 years and in that time I have only made him cum 2 times with oral.. he never lets me finish him off he says he has to because it’s to hardcore if I do it. The other night he asked if I would try something new with him, so he put on a porn video of a girl giving a guy a hand job and told me to follow what she does. This makes me uncomfortable and upset and it also makes me feel like he’s not attracted to me because he always has to finish himself off.. any ideas on what to do??
