Love? or is it really just friendship?

For a little over a month ago I got my first real boyfriend and I really like him. But I'm not sure that it's really love, because I don't really want to kiss him or anything, but I'd rather just do things like talking (about anime or music or something like that). He's 3 years older than me, but kinda on the same level as me (girlfriend/boyfriend wise). He really is very nice to me and doesn't expect anything to fast, but he tells that me he loves me a lot and I can't reply because I don't know what loves means, so I can't make myself tell him that.

I'm having doubts about whether it really is love or it's just friendship and that I maybe should tell him that I just want to be friends.

Anybody with some experience on this specifically? Advises? anything would be nice?
