Partner doesnt travel well

I (25F) love to travel basically anywhere but my partner (24M) either doesn’t like to travel or doesn’t travel well. Sometimes he gets nervous in a new place, can’t eat anything for days, and has GI issues. He seems off and just wants to go home. I haven’t traveled anywhere with him in almost 3 years but I’ve solo traveled in and out of the country many times. I’ve tried to have conversations about it but they don’t go anywhere. Any advice on conversation points or how to make travel more comfortable?

EDIT: everything else in our life works well and there’s no underlying issues. he gets anxious when he travels somewhere unfamiliar. I’m asking for advice on how/if there’s ways to facilitate being in new places together.
