The experienced boyfriend

So me and my boyfriend are both 16 and we have been dating for 3 months and he’s done everything in the book except oral and sex. I on the other hand haven’t done anything except for him sucking on my boobs. He says he loves me and he really does he makes me feel special but idk what love is I’ve never experienced it I just get sad because he’s done a lot of stuff with girls but he said he cares about me than anyone else and he tells me he wants to marry me one day and I love when he tells me that. I just don’t know what to do to shake the feeling off of how he’s experienced.

Any tips ☹️
