First kiss and kissing.

Hello everyone! I'm autistic and I'm planning of kissing my hopefully soon to be girlfriend. I haven't had a relationship prior so I haven't kissed anyone before. I feel like I know how to do it, but I'm scared to mess it up! Where exactly do I place my tongue? Do I just reach in her mouth and put it up to her lip (if kissing upper lip), do I do circles with her tongue? lol like can someone give me very specific details please 😔✌🏻✨💅🏻
