sos 😶😬

so i am dating this amazing guy. he's kind and funny and smart and is perfect for me in every single way. i am 15 and he is 16. we live about an hour away from each other and rarely get any time to hang out with each other. recently we've started talking about having sex, but i'm not 100% sure i want to. i mean i love him with my entire heart and he makes me feel like i am on cloud 9. but if i'm not 100% sure, should i go through with it? if i don't should i give him a bj so he's not completely disappointed? what should i do??? 😬😬😬
