Depends on the friend. If it was someone I might be interested in then I'd say yes. If not then I'd see how the kiss felt before deciding. I think you need the right setting. A doorway saying goodnight, in deep conversation sitting close together on the couch, after a warm embrace....yeah....that's it... after a warm embrace! You hug and slowly pull back, but not to much, you look into his eyes and lean in a little. If there is no pulling away, then you lean in more and slowly...gently...lightly...kiss on the lips. If you have gotten that far then your friend is likely on board with you. Another kiss would likely be wanted and you'll both know there is a chemistry heating up.

I was asked for a kiss several times in my life. It was kind of nice the first time but with every guy after that, the question broke the mood a little for me. I don't know why because it's a very sweet gesture. If you feel right asking then do it. I like the passion of "feeling" the mood and timing is right and going for it.
