Is it possible I could be falling in love?

So just for background reference, I am 20 and have been in love only once before. I can typically tell the difference myself between liking and being in love, but this time I'm not sure! It took me over a year to fall in love with my ex boyfriend, but I've only been seeing my new boyfriend for about a month (we only started dating officially a week ago. Before that we were intimate but not exclusive - we are now). I'm not one to get swept up in sex either, so this is so strange to me!! I've only known him a month and I feel like I've known him forever. I've never believed in love at first sight but my god this man has almost changed my mind. I don't want to freak him out (honestly it's freaking me out!!) but I've honestly almost dropped that I love you bomb about six times already by accident - I don't know what is wrong with me!! When only been together a month!!!! Usually it takes way longer! I'm so confused!
