This is very heteronormative and gender binaried. Queer people exist and date.

That said, anecdotally, from the handful of women I've talked about this with: many don't like making first moves on these apps.

Using dating apps is a skill, and if you haven't been practicing sending messages you're going to be bad at it. The vast majority of first messages I got from women were "hey". Trash tier. Probably because they just haven't done it very often.
