@Heather I did think this as I understand not everyone’s love language is the same however he says “he doesn’t know what his love language is” he rarely shows me any love to be honest other than sexual
I'd sit him down and have him take the quiz and then have a conversation of how yall can compromise so both of your needs are met.
Not to sound rude but could it be because of how he was raised? Like say his parents didn’t give him a lot of affection as a kid, some people grow up not knowing how to actually give affection. It would be worth finding out if you don’t already know. Breaking down your own walls can be hard if you’ve built them so high. But in that case I can only suggest he gets personal therapy. I know everyone is different and some people do not like those things at all. Some people have conditions and there are a lot of other things. I’d be asking the question was he always like this or is this new and then go from there really. I would say for a lot of people it does come naturally because it’s a lovely thing to be able to do with your partner. But for others not so much but there’s always a reason
Have you looked into both of your love languages? You could be two different types of love languages.
