Such actions aren't seen as an affront to ladies but rather as a sign that Dutch men see them as equals – although some might say this is the unfortunate downside of equality when dating a Dutch man. Part of this has to do with the prevalent bike culture – have you tried biking in high heels and a mini skirt, through the rain?
It also comes down to the Dutch laid-back attitude, which tends to extend to clothes (and makeup), so you may want to take it down a notch if you're used to getting very gussied up for a date.
Being successful in Dutch dating can require a level of assertiveness: if you want something, just do it.
The Netherlands has less of a dating culture than other countries, for example the US or UK.
You can find that both Dutch men and women cut out flirting and small-talk in favour of simply stating one's desire or intentions.
