This is an interesting game, and can be fun. Things that would be good to see though.
More customisation to the people in your world such as only of a certain age group, e.g 18 only, 18 to 25, 25 to 30, 30 to 40, etc.
Add Tattoos and piercings.
To see how many people are at a location before you visit on the world map, sometimes you go through loads of locations before finding someone to interact with.
Of course more sexual scenes that fit in with the fetishes, e.g. if someone likes dirty sex then add something dirty to the options, e.g. comments around receiving oral after anal.
Further voyer and exhibitionist options, sex in public can be in public not just in a toilet, being watched/caught being a turn on.
Display further stats on your phone such as heights.
Add the ability to message not just call and an option for sending and receiving sexual pictures.
I am not sure how the pay for sex works, I see a greyed out option for it, when you offer.
That's all I have, just feedback, keep up the good work.
