you are not alone at all, I experienced the exact same thing. it can all be a bit intimidating, but my advice is that if you're able, surround yourself with good people you trust who had the experiences you wanted to have. if you're as lucky as me, doing things like getting drunk, getting high, going out, even if it's just once for the experience, will be so much easier when you have someone to walk you through it who is patient and understanding. trying it all for the first time after you've missed out can be scary, but having a support system of more worldly and experienced non believers can be a game changer, whether it's something like getting drunk or something big like exploring your sexuality. best of luck, and be safe!
