First Time Sex Anxiety! Advice + tips?!

I'm an anxious person in general, but recently I've been having a lot of anxiety just thinking about losing my virginity. I can't stop thinking about STD's, pregnancy, being naked in front of someone else, queefs (lol), whether to do it with the lights on or off, etc.. I've never even made out with anybody.. what if I do it wrong 😂 There are just a lot of "What If's" to think about. Do they ever go away? Is it kind of like what people say about having kids - you're never fully ready? I don't feel pressured and I'm definitely not in a rush, but I just need to be able to reassure myself for when it actually does happen. Also, please share any first time stories or tips you have as they would definitely be appreciated!!!
