There's one somewhat odd thing I'm noticing, and I'm not sure if it's unconscious or intentional, perhaps even part of the story progression. The MC appears to be very... indirect? hesitant? uncomfortable? in sexual situations. I am most definitely not that way when playing games that are clearly intended to be NSFW. What this means is that I pause for a long time on choices of that nature, and often end up reloading to see both options, because I'm stuck between wanting to make the MC less hesitant, or wanting to preserve a sense of immersion.
You've mentioned that you felt like your MC is letting his dick do the talking too much... I honestly felt it's been the exact opposite from the beginning. So I'm wondering if you're unsure of how the MC comes off, you're trying too hard to rein him in, or... maybe it's just me being excessively horny all the time.
