losing my virginity

so I have a feeling that i might lose my virginity soon, because this guy and I have a thing that’s been going on for a while & we’ve made it obvious to eachother that we like eachother etc

but the thing is that he’s experienced and I’m not, and I’m just nervous about it all. I don’t know how to do anything and I’m scared of not pleasing him or just bailing from the whole thing. I do want to have sex with him, but I’m just scared of being disappointing or doing something wrong

advice pls,, how do I prepare myself for it?? also will it hurt?
