Is it normal that I get scared when my boyfriend wants to kiss me?

You can wait. How many times have you actually kissed? If you haven't done much yet, you should give it another shot. My now fiancé messed up our first kiss LOL he literally had too much saliva in his mouth when he went for it. I immediately was a bit weirded out by it but then it never happened again as I gave him another chance soon after. Maybe this guy messed up the first kiss? I feel like even though you think you love him, if you're afraid to kiss him, something is up in that heart of yours. Maybe he isn't the right guy after all? I'd just give him more time. You've only been together a month!
