Can you please help me i think my (male friend) has a f00t fetish?

he is gay but thats no problem to me. but the other day we were hanging out and playing video games, i was sitting on the couch and i took my socks off and he moved onto the floor near my feet, well soon after he pretended to "drop" his controller near my foot, i noticed he smelled my feet while his head was down. then he said "want a massage?" and before i could answer, he grabbed my feet and rubbed them real quick but before putting them down took a big whiff..i just laughed it off but im curious, do you think he has a feet fetish? are these sings? i know its silly but im just wondering. thanks
