I really need help??????? Please

So I recently got with my boyfriend I’m 15 he is 15 going to be 16 in a month. He wants to wait to have sex (which I’m OK with) but like I said his birthday is coming up and I don’t know if he wants a blow job or anything like that. He knows I’m not a virgin and we talk about sex before we got together that’s how I know he wants to wait but idk if you was just saying that to be nice or if he actually meant. He’s very respectful he’s never touch me in appropriately or asked me to send nudes so idk if he wants anything like sexual for his birthday. Can I get any advice or help how to ask him or how to hint around
