I am 47, I have kissed a few times and been kissed a few times.. I notice with each lady I kiss it depends on the situation, our surroundings, the atmosphere and the relationship with the person, as to how the kiss should be..
Say you see a friend of the opposite sex you haven't seen a while.. Is it PC to give them a quick kiss on the lips and a hug or should you just give the hugs and a peck on the cheek?? Depending on how close a friend they are would detemine the kiss..
You meet a lady that strikes your fancy.. In a local establishment that has a dance floor and alcohol.. A. Do you buy her a drink or B. Do you let her buy her own drink and offer conversation?? I myself feel you should let the lady buy her own drink therefore she does not feel like she may later be indebted to you.. Have conversation always maintaining eye contact, thus showing interest.. Above all be a gentleman.. If she goes to the ladies room, stand, pull her chair out and sit down.. If the bar is crowded ask
