I haven't been able to orgasm?

Me and my boyfriend got into an argument three days ago, he's apologized and promised he would never make me feel like that again, or act like that again. I've forgiven him. But since then, I haven't been able to orgasm. Before the fight, he's been able to make me orgasm every time. We've had sex about 5 times since then, but nothing. He's getting frustrated cause I can't get close. Is it a mental thing for me? It sucks cause I really enjoy it and it's been awhile since I've orgasmed.
