Speedy Relationship

me and my boyfriend have been together for a little over a year and mostly it's been really slow. I haven't had my first kiss at all, let alone with him then up until about a month ago he kissed me and now we have like make out sessions.. (Warning TMI) then all in the same week (three days) we have had a full on make out session, he fingered me, I touched.. yeah you get the point. anyways I've never really done that stuff with him or anyone for that matter until a couple weeks ago. now, he wants me to give him a blowjob  and then he wants to have sex.. advice? I'm 15..
