Guys, Why does he kiss me all the time?

I started dating this guy a week ago and he‘s very nice, a very good guy. He always opens the door for me and holds my hand and refuses to let me pay for anything but I noticed that he likes to kiss a lot like really a looooot. When we‘re out in public he kisses me like every 2 minutes, even when he’s on the phone he kisses me 2-3 times during the phone call even if it’s short. He also likes to hold hands even when driving his hand is on my thighs or holding mine or he puts it on his mouth to kiss it. Sometimes I‘m scared that he doesn’t want anything serious because of that. He also doesn’t talk much and just wants to hold and kiss me.. makes it feel like he just wants to get physical but on the other hand he treats me like a princess, he‘s kind and considerate and he still didn’t cross any boundaries but I’m still scared that he just wants to get me to sleep with him.. any advice?
