Hello! STDs are still there, but the chance of catching one is pretty low. In terms of clients, only elite clients can currently pay for unprotected sex, and it's very unlikely that they will. I'm trying to make the disease system less punishing and balance it a bit better. In previous builds, diseases were brutal, characters kept dying all the time. There is a lot of consequences for a dead sissy in the game, even though it's not being fully utilized right now.
Also, this is a very basic version of the escort business, essentially without any consequences (for example, if a client catches an STD from your worker, they won't care). It will become much more complex. I don't want to overwhelm people with it at the moment.
That being said, no, you are not missing anything. It's me trying to figure out the best way to implement diseases. Thanks!
