Guys during quarantine

I’m a virgin, and the guy I’ve been talking to is not. And we’ve sent naughty texts etc. and everything he says sounds absolutely amazing but what if I’m not good? (Both legal age) He says he wants to make it special and that sounds great. I just want sex but my main concerns are. Tmi. he says he wants to taste me and eat me out. Ofc. I want that who wouldn’t? But how am I supposed to taste or smell? It’s not like I have the knowledge, I’m a clean well kept person but still. I’m also concerned about his size, I know lube and being wet first but he is umm, well endowed especially the width? But I also wanna make him feel good. Basically this post is verbal vomit of a girl with concerns on losing her V. I’ve known him for years and I want it just all the unknowns are terrifying, he knows I’m nervous and when we can actually get together I know him. Along with being inexperienced I know from self pleasure that my clitt isn’t very sensitive, it’s quite small. Also.... head? Any advice help a girl out! I have a sexy black teddy lingerie but I don’t know if I wanna wear that for the first time.
