How should I handle myself in this situation with a boy?

I’m fourteen and I met a guy at my church who is fifteen and he’s really cute and nice. Yesterday he told me he liked me (which was kind of strange since we met just a few weeks ago) and I told him that I think I like him but I want to get to know him better, and he seemed okay with that. We flirted a lot and we text a lot and I have a lot of fun around him and I think I like him! Now he’s acting like we will be in a relationship soon… which really excites me cause I’ve been single for a while. Then he asked me if I’ve ever kissed anyone (and I haven’t) so I kinda got embarrassed and changed the subject and asked him if he had and he said yes, he’s gone even further but not “all the way”. (which was kind of disapointing) So he asked me my boundries and i said no further than second base.. and it just became really awkward. He was like “okay.. fine with me” and then he said he had to go. Did I scare him away?! Please help, thanks!
