virginity

so i’m only 15 and my boyfriend and i have been dating for almost a year and we’re both virgins. i told him i want to wait until we’re a little bit more older to have sex just because i feel like i’m too young for it but also because i’m not physically and mentally ready for anything like that. but he turns me on so much and i always wish i can have sex with him and stuff but i just want to wait until i’m older, has anyone else felt this way? i get it’s my hormones making me feel this way and stuff but me wanting to wait and me not being ready is the only thing holding me back. like i always want to have sex with him but i just know that i’d be too afraid
