It is optional, the player is able to decide.
Nice to hear, I guess it was mainly because of the money-tight-story that the thought came up it may be mandatory

Personally I hope I can have her make porn with other guys even, kinda the ultimate sharing :x XP
Hence why the plot progresses faster than other games, I am too impatient

.
It is honestly refreshing in my opinion... there is nothing wrong with going into the action fast, you still portray the feelings between the MC and the girl very well and I mean, we are here for porn in a sense, it is fine to have some porn logic to bring things faster forward then seems realistic by having her that open from the get go
Trust me I want to work on this game a lot more, it is genuinely the most fun I have had in a while. But I make everything by myself (writing, images, coding, optimization, bugfixing), I don't have a team of people. It is just me working after I get off from work, or on weekends. During v0.2 I had more time because I was without work for a bit, but now my work load has increased.
I am happy that people are impatient for releases that means I made something that people like. So, I will try to take less than a month and a half of each update. Right now my goal is to get an alpha version release by the end of next week containing 3 of the 5 planned scenes, so you won't hear from me as much.
Well, congratz to getting back into work, even if it sadly means less frequent updates q.q

And while I hope for frequent updates, don't rush yourself either, sometimes it doesn't work out, better take longer then throw out a unfinished thing

Looking forward to what will come, gonna look that I throw a bit on patreon too, was really positively surprised here :3
