Im scared

Okay so im a virgin and i wanna fuck this guy😂 he is only a year older then me and he hasn’t asked me for anything ( pictures, to fuck him). Im only 15 ( i know thats a bit young but im saying this in the nicest way possible... it doesn’t effect your life so can we please not comment about that. I know about protection and all the things that could happen). Okay so what if he thinks im to fat of like i make weird noises or something like that... im scared but i really want to do it... do boys care about that sort of stuff? Like what if he thinks my vagina is ugly🤷‍♀️
