How do you make dates not feel platonic?

Hello autistic lesbian here! I find I often get friendzoned but they actual do want to be friends afterwards so I wonder if I give off a friendly vibe as opposed to romantic. What are some things that you do to make the date more romantic? I’m proactive about planning dates that link to their interest, I perhaps don’t openly express if I’m excited to them.

Are there specific topics of conversation you try to include? I don’t tend to plan my questions I just let the convo flow. Maybe I could try include a funny story

What are some ways of flirting that you look for to see if they are interested in you?
