Should you ask someone's permission to kiss them?

[Odin]

A decade ago I could have said no.

[Bobby Martnen]

Only if you're an emasculated cuck with exceedingly low testosterone levels.

[Tom Cat]

If you want to face charges for sexual assault, go for it.

Remember to be a gentleman, and mind your manners. Ask first.

Also, be sure the lady isn't married, or the husband might rearrange your features, which is exactly what I would do if some jerk suddenly grabbed my lady and forcibly kissed her.
