Boyfriend problem (please answer i need help)?

ok so i stayed over at my boyfriends house last weekend and we were fooling around in his room like making out and then he got really touchy and start to try and take my cloths off, i let him take my bra and pj shirt off, then he worked his way to my pants. i stopped him every other time he tried to do that, but not this time so yea.... u can see how far we went, so then he asks me. if i wanted to have with him, and im still a virgin and so is he but im only 15 so i told him no i wasn't ready to go that far yet, now i sort of feel bad that i told him no, did i do the right thing, because i know im ready now, and i do want it to be with him
