What should I do in this case?

So I match with this man on a tinder. I DM him and he gave me his IG. So we talked there. This man is super attractive and his IG have so many followers but his following so low. We talked and he keep asking me if I wanted to see him he'll pick me up.(at night ) But I want a real date. After a few weeks we texted and we meet at the coffee and talked for awhile. He's super hot and we get along. He's seem like a gentleman, funny, he's always be sarcastic with me. He paid for the meal and we walked around and having fun talking. But he's asking me if I wanna go for swimming at his place since we get along. I told him I haven't prepare for it but he tried to convinced me but I still rejected so he's just stopped asking me. Then he walked me to my bike and finally we kissed goodbye. After the date he text me "it's chill"
Tomorrow he texted me again asking if I wanted to swim at his place. I wanted to go but I've just met him and I'm feeling like it's not safe. What should I do to get to know this man better?
