I kissed my girlfriend and she said it felt weird.?

[Dork]

Alright i kissed my girlfriend not to long ago, it was our second kiss. The first time we kissed it was great the timing and all that but this time it was good but i dont know. I kissed her and when she left she told me her lips felt weird i didnt use any chap stick or anything just my soft lips lol she said they felt warm and tingled. Idk if its a good sign or a bad its our second kiss together so idk if its just because we are new to this or if im bad at it. When we first kissed she said i was a good kisser so i dont think its that but im not sure. help plz
