Hey guys how are you? This question might be ridicules but help me if you have any ideas. So my girlfriend refuses to kiss me on the lips! I mean she says "it mess up with my head once i do it" and she also thinks it's kinda a sin. It's our first relationship for both of us. BTW, we're both protestants and if anyone with knowledge from the bible who could help me figure out if it's really a sin and i should also stop thinking about it or it's normal? And anyone with person opinion without the bible you're also welcome to answer Thanks guys.
