I completely agree with you. I believe I have a healthy sense of humor, but I find absolutely nothing humorous in a man asking for a kiss on the first date.
Now, a knock knock joke, sure, it can be funny. How many ? does it take to change a light bulb? Love those. But it a man asking for permission for an intimate act? Nope, still nothing ha-ha funny at all. Considerate, yes. Kind, yes. Correct, absolutely.
When in doubt — ask.
