At least the game plot seems good, I like the adventure and fighting. The MC seems to be still stereotyped like other games but I still hope there will be many other strong male characters who will do better than the MC! What I wonder is exactly as you said, why most sex scenes in most games only revolve around the action of sucking cock and the male characters just basically rush fuck and cum instead of caressing, exploring, enjoying the bodies of female characters, especially they often don't care about the breasts, sometimes they don't even bother to take off their clothes but just rush to find any hole to ejaculate.
		
		
	 
I'm not gonna lie, you advertise MC he is like a loser, I'd say exact opposite, You need to know when to fight as well as when to flee.
And again, just like aspect of reality and logic, Sometimes there is things with difficulties, you have to try to change somethings.
Keeping distance with others or find people hard to trust, something every human being with intelligence would do in my opinion. He know his limits and would push every inch of his power to achieve what has to be made.
This project is not; 
'Sex with every human being in sight'. It have a story to tell and goal to achive. 
Creating a bond with them first is much more important for my storytelling... 
If this is your type of flavour, I'm really sorry. 
And about the sex scenes with other here's my quote to other user I described the situation:
""When I first designed characters, set two side of who will get sexual content while having a love interest with MC and who will get sexual content without love interest with MC.
Gin and Sonrose was part of the non-love interest.
Since I'm working overhaul the story and characters, Gin is now at side of the love interest with MC.
Also with CH3 all sensitive content will be avoidable and FYI harem not yet implemented my game. It's planned tag.
And no, there will be never NTR in this game.
Hope I can remove quesion marks for you."" 
Thank you for your opinion, Much Love <3
