Forgot to ask, could you do a online version for easy phone access too?
In my opinion.
About the confirmations.
Yes and no. Maybe it is a bit repetitive and feels like clicking on a confirmation from a settings menu. You really want to save your changes? Adding variety to how she asks and react on your choice would be preferable and only a few clearly confirmations. And the situation where she already told what she was doing (dipping toes) does not need several confirmations for a picture.
Having credible acting characters is important but always keep your target group in mind too. Someone who is playing such a game that far won't say no and the question should only appear for character development.
About her feelings and the details.
I would combine these two. Was she nervous on the way to the bathroom? Was she horny? Did she had a drink? Did he make her compliments. Did she let him touch her to get in mood before going to the bathroom? Was his cock warm? Was he already throbbing? Was he already stiff? Did she note this as a compliment? Did they dance close together? Did she feel his breath? Getting goosebumps? "I was feeling his gaze mustering me. I was really nervous and got weak knees on the way to the bathroom 馃槵 ... at least I had no problems to get down on them 馃槒"
Sorry my English hope you get the message.
For the social app an idea is to make her write a hotwife blog with counters and sharing her experiences in short texts and interacting with comments additionally to her dating profile with changing interests. Or replacing the profile with the blog on further progress.
