What to do?

So I went on my valentines day date.. He was waiting outside the resteraunt for me with flowers and a card! Bearing in mind this is the first time I've met him. He was so nice. Incredibly nice. So nice that I'm on the verge of tears right now. But I don't feel in love and I don't feel love! What's wrong with me. He's perfect. I've never had anyone be so nice to me- he was asking me so much, really interested in me. He was saying how pretty he thinks I am and how he loves my height its cute etc. He mentioned about what we could do next time. Should I let a next time happen? I'm not sure if I like him. I really don't want to lead him on, he deserves the best in life:/ I don't know what to say to him. Is it normal to not feel love on the first date? I felt aroused when I imagined doing stuff with him and when he touched my leg/hand😂 I never feel a romantic attraction for any guys, what does it even feel like? I'm so confused aha !
