first timer

so i’ve been seeing this guy for a month and a half now (we dated twice before this lockdown thing) and we’re still talking. He opened up one night that he’s horny and stuff and he wants me to send him nudes but i told him no and he said sorry the next day. Now, he wants us to meet for dinner at his house and obvs he wants us to have sex already. I don’t know what to do bcs I haven’t had any sex yet (im 21 btw and he’s 25). what should i do?
