Having sex outside of marriage is wrong. I don't recall saying anything about kissing, unless you're talking about kissing other than kissing on the lips.
Frankly people are free to do whatever they want. I discuss my beliefs and do my best to follow them. I understand how easy it is to do immoral things, and that people can find they enjoy it. Enjoying something doesn't make it right.
Unlike some Christians, I don't care to force morality onto people, particularly through the government, who I find to be anything but moral.
I do share my beliefs, but people are free to reject them. I find it difficult to live a moral life. I make mistakes, and I try to do better, that's all anyone can do.
I don't ask people to be perfect or expect it, as I'm not perfect nor capable of it. I do discuss what the right thing is to do.
