I don't know how to get started but I'd really like a partner and one day I would like to think seriously about children.
I've never done anything, not even hold hands, and I'm in this horrible cycle of worrying about my inexperience and letting it hold me back. I have a Hinge profile, and I've been on dates, but whenever I've liked someone, I've felt more awkward because I'm so worried about looking like an idiot if he tried to kiss me. I don't know how to do it 
This sounds especially ridiculous, because I know how silly it would be to go to someone's flat etc without knowing them, but I always feel like 'the goodbye moment' happens so publically and it feels humiliating.
I don't have anyone to talk to who understands. My friends all did this when they were 15. If they go on dates, they're thinking about having sex on the third date, not worrying about a kiss.
Any advice at all would be so so welcomed.
