Sex based rights are really human rights denied to half the human population because of no reason other than their sex until they fought for equality... at least until a new wave of males came and started stripping us of those rights again.

When female people (other wise known as women and girls) refer to sex based rights they mean equal rights in comparison with the opposite sex. They mean the equality, safety, and dignity almost always given to males (note- specifically in comparison to females, not in comparison to each other) simply for being males but often denied females simply for being female.

When the term sex based rights is used in the context of genderfeelz and trans people- it means that female humans should be allowed to have their rights remain undisrupted by any male regardless of their reasons for wanting to undermine those rights. Stated plainly- it means TW leave women and girls entirely the fuck alone and rally for themselves. Not because we are mean and don’t want to play with them- but because they literally are disrupting our rights (amongst other reasons for sure, but let’s stick to your post topic).

Aside from abortion and menstruation supplies… which not every female has access to for what it’s worth…

Equal pay

Equal opportunity

Equal representation

Dealing with male violence against females (in all its various forms)

Dealing with rape culture and how rape is handled generally

FGM

Sex trafficking

The ability to have a SAFE abortion

I’d throw in the ability to not be forced to be classed alongside our oppressors but that’s not officially on the list…

That’s just a few of the other concerns

It’s not about women needing things that men don’t need- it’s about fixing the system so that women have equal footing and just as fair a shot. Women don’t really have anything men don’t have (in this context lol).

Women are literally trying to balance things out so that everyone starts out at the same level and has the same access and opportunities regardless of being male or female

(I’m sure someone will offer a deeper response, but I tried lol)
