Let's start with the fact that a person of the 21st century owes nothing to anyone. Neither man nor woman. The site constantly raises the topic of beauty standards (or rather stereotypes) and always promotes the topic that in matters of personal beauty no one should tell you, which I fully support. Shouldn't, if you don't want it yourself, if you don't like it or it brings discomfort. But you should listen to your couple's opinion, because this is all subjective. Someone may not like a hairy chest, while someone does not care about your unshaven armpits. Do not listen to people around you, listen to yourself and the person who is really concerned.
If a man wants his woman to shave armpits and other secluded places, then he must at least match. I'm not against vegetation on men, but within reason. The hair in the armpits can not be shaved, but cut, for example, and washed for hygiene. Secluded places in my opinion look better shaved, but here it is already as anyone. I will not cry and run away if I suddenly see an unshaven pubis. (again, provided it is clean and well-groomed.)
