<human>: Is this normal for someone who has never kissed someone before? because I'm flipping out.

I knew this guy for 4 years, liked him for 1.5 years, we've been dating for a month now. This whole time I never kissed him on the lips, but stuck to the cheek (good girl faith here..) and with the cheek I get turned on!

Im really attracted to him, and he's my best friend! But just last night we shared our first kiss and it was NOT what I was excepting.. 
It was wet and slobbery and he jammed in tongue right away; it was kinda gross to be honest. I felt SOME passion after we kissed more, but it wasn't how I expected it to be. Its kind of making me worried that I don't mentally have interest in this guy. Because although I felt some passion, sparks didn't fly.

I only kissed one guy before when I was 13 and it was a little peck, and that really made my head spin. But the guy wasn't for me at all.

Now I have this sweet, first boyfriend, and I'm afraid everything's ruined. 

What do I do? Please give insight and experienced you had !

<bot>: Kissed boyfriend on lips for first time, not much passion and felt sorta gross. Afraid I mentally don't like him. I just want to know if this is normal for first kissers?
