Mommas boy?

So I've been dating this guy for almost 6 months, and let me just say he is an amazing boyfriend, but I've heard nightmare stories about mommas boys and I need some advice. His mom is super nice, don't get me wrong, and him and his mom are much closer than he is with his dad. But sometimes it's a little strange to me. Like before his races (he races dirtbikes) she'll kiss him on the cheek, one time it was on the lips tho which was weird as hell to me, before I do, and he said that if we move out and live together he's gonna get a copy of his mom's cookbook for me cause he likes her recipes, the woman helps him put his contacts in if he's struggling?? And when I got my underboob tattoo she interrogated me about it and asked me if I thought about where I got it cause it'll stretch when I get pregnant, I'm twenty and I don't plan on having kids soon soon. He's 24, he has a really good job and is eager to move out, and he makes his own decisions and everything, idk is it just me? I'm not particularly close with my family (it's a mentally and emotionally unhealthy emvironment for me)but should I be worried? Or talk to him about it?
