i need advice

hi everyone, i need help. about 2 months ago me and this guy started dating. we’re really close and get along perfectly. and i know this sounds insane and you might laugh at me for this, but i do think we’re going to last for a long time. (we’re both currently freshman in high school, he’s turning 16 over the summer, i’m 15 turning 16 in october) he keeps telling me that this summer he wants to lose his virginity with me over the summer. i tell him that we’re to young and that i’m not ready. he says that he respects that and i know he won’t pressure me into anything because he knows how bad my past is. i really do like this boy and i want us to last but i just don’t know if i’m ready to lose my virginity... can someone please leave advice!!!
