New guy has a fetish

So this new guy I've been talking to is the biggest sweetheart. He's a local artist and we really vibe. We aren't trying to be in a relationship though and are fine with a friendship/situationship. We've had sex once already. He told me he has a foot fetish. I'm not here to shame him, really just here to learn. I've never met someone with a foot fetish before and idk how to act lol. I don't mind to be open to it. Does anyone have experiences to share with their partners having foot fetishes or advice on how to be more open and less shy?
