There are women on Grindr - in my experience, mostly trans women or m/f couples looking for a third. So men can find straight sex on Grindr, but it’s rare. Women are definitely a scant minority of the users.
There are plenty of “straight” men on Grindr. You’d have to ask them why - I usually block them.
The reason why dating apps marketed towards straight people don’t allow this kind of messaging (and the reason there aren’t more women on Grindr) is because women, generally speaking, won’t put up with the same kind of shit that gay men will. A straight dating app where men could send horny messages and dick pics to every woman they saw wouldn’t have any women using it.
The world lost untold weirdness when Craigslist took down their personals section, cause that’s where my down dirty girlfriends were getting the dick back in the day. You could go on and have your pick of dozens of guys in an hour. Generally they were real guys. Most were awful but they found some diamonds in the rough.
Why isn’t there a straight version of that lol
Multiple answers to that question:

Or it would have the horniest, sluttiest women in the world 🤷♂️
