How should I feel.

I am 18 years old. I've never really dated. I am now dating a guy . He's 18 as well, has his own house, car , a job. We started dating a month ago. I feel like he really likes me. He always tells me how beautiful I am. When he takes me out we hold hands 24/7 ( even when he's driving) I always catch him staring at me. He's met my mom , my uncle but i haven't met his parents. Should i be worried ? We had sex for the first time last night.. what do y'all think ? does he sound ok ?
