BORING BOYFRIEND IN BED

My boyfriend doesn't do anything fun during sex, nor show any interest in it.

He get uncomfortable during sex scenes in movies and TV, we went to a sex shop once and he hated it. He isn't interested in me dressing up, role play, tying up, toys, props, nothing. He isn't spontaneous or adventurous. His idea of rough is pulling my hair. All of my friends' boyfriends love it when they dress up, they have rough, spontaneous sex, and have fun. With mine, I go down on him, we have sex, then as soon as we're done he gets up and cleans off his dick, then goes on his phone. We also used to last for hours, now the entire thing I done in half an hour.

Any advice? I just...feel like he doesn't enjoy it. He swears he does but his actions show differently. Help?
