He hugs me tightly, his heartbeat is increased everytime we hug, he gets erection, he kissed me passionately after some emotional conversation,?

I have always felt like he has feelings for me. But due to some reason we had some fight and angrily he said it was just lust for me what he had. But i didn't feel through his body language that its lust. Does he really just had lust? he breath deeply while hugging me Are above mentioned body language of his sign of just lust? Can a guy have such feelings for any girl or only the girl he loves? what are the physical signs of lust?
