Guy I’m dating rarely kisses me?!?

I’ve been dating this guy know for about two months and we are exclusive and I see us starting an official relationship soon especially with how things have been going. I’ve noticed when we first started to date we would kiss a lot and we both aren’t PDA but definitely would get a peck or two in. Now I’ve noticed he barely kisses me and he has told me he doesn’t like PDA a lot but you know even a quick peck would be nice. Are some guys just like that? He holds my hands, hugs and twirls me around and we definitely act like a couple. I’ve asked him before and he simply says “I don’t like PDA.” I totally respect him not liking PDA , but also just a small peck when we say goodbye would be nice you know!
