I'm a boring cishet so take my words with a grain of salt, since they mostly come from conversations with some friends of mine:
Be aware that apps such as Grindr often host people who are very active in the app and very horny. This isn't something intrinsically wrong, but some people are just a bit unhinged and have no boundaries, and will be very overtly sexual from the start. If that's something you wanna engage in that's totally fine, just be ready for a likely wave of sexual attention if you open an account.
