First real serious bf?

we both are still virgins. we been dateing for a month starting wed. but have been not offically dating for a month before. we got to the point were we started kissing. i get really excited when he does that and keep wanting to get closer. i found that hes really ticklish. so i tickle him while i try and kiss him. though today i got chills when he kissed my hand and my neck. when we kiss he and i dont want to stop. when he kiss my neck several times and went down to my shoulder i got really scared. i seriously didnt want him to stop but we both kept pulling away. its really hard. does this seem so soon?
