My partner has a few gay friends that he's known for years. He met them all through a friend. I went on a night out with him and them recently and was quite taken aback to see him greet one of them with a peck on the lips and then later kissed the same man on the hand at the bar. He's a friendly jokey person in general but am I right in thinking this is a step too far and a bit unnecessary and inappropriate, especially in front of his partner?
