My boyfriend didn't want a handjob, what dose this mean?

Ok, hi, so first or all I'm a virgin and so is he, we have been dating for almost 4 months and we lost our first kisses to each other and I have never done anything sexual with anyone else other than him and vice versa. 
So one day he was fingering me and I asked if he wanted anything in return and he said " I don't want to put you through that", is this bad or good, I thought it was good but my best friend said otherwise, what could this mean?( btw we are both 15) 
Pls help
