Hello.
Just some thoughts about the 0.5.0 and after.
What is the difference between polyamorous and non exclusive? Also, how to unlock those characteristics outside character creation? Because I'm more interested in the third option usually but that doesn't mean I don't have the sexuality of my MC in mind (you may have not found the right partner(s) to fool around before but that doesn't mean you don't know what interests you). I'm trying to go after as many people as possible, without hurting them or being hurt (everything should be consensual and decided through discussion beforehand).
For already existing couple : I understand some don't want to cheat but maybe they could be interested in a threesome.
I stopped the best friend storyline since I don't know what's the best between boyfriend and fuckbuddy. I prefered how it was previously : testing to see where it was going before deciding (I know what I want but I don't know what the best friend wants).
If we're invited to stay at someone's house after sex, there should be a way to eat something (either having some granola bars on us if we have a backpack, having something in his/her house or being able to eat before accepting to go out). Because being invited when our food bar is low means we can't stay and I don't want to hurt them by declining their offer (it was the day the best friend invites us to the River Rat; I was drinking when offered or just chatting and wanted to eat before leaving or from the food stash but, when invited to someone's house, we have no choice but to accept (or not), which prevents us from being ready (rest, food, bladder, hygiene)).
By the way, in that person's house, there should be nobody besides him in the People Here section :
It's strange that the people from the River Rat are in his house

.
Why the price of those increased? It made them lose any purpose (the ratio price/satisfaction became uninteresting with that change).
Some ideas :
Not sure if it's already implemented but :
Fingers and toes licking, neck licking and kissing (both front and back), abs and navel foreplay, even biceps worshipping.
You need to check Additional Body Hair in Options
Does it have any use other than grooming? Also, will NPC body hair be available at some point?
It has been a while since I played, could anyone answer me something: can you be the top on male/male STORY CONTENT? Because I remember that both in the roomate partner and best friend the narrative is you being the bottom and I don't like that.
You can be top but not with every character. Some are exclusively top/dom and will refuse position change during sex.
After that I think you just need to continue hanging out with them with the "talk about sex" option.
I always have the "talk about sex" option the first evening if his roomate isn't there.
Correct one is with Photography skillcheck - you have a reliable way to up photography skill by going to a library and reading a book to pass the skillcheck, however long that might take
It also increases when you take selfies.
Are there any other world seeds that alter NPC behavior other than the initial 3 it gives you in the help section?
Every world seed alter NPC behaviour. We just don't have enough information on what others contain. There are some comments in the thread about the seeds they tested.
Good continuation.
