Can you make a slight change to the story? I think it's a bit dumb that the MC is effectively a super human at the cost of his Sperm no longer working ( reminds me to much of the Fallout super mutants), it would make a bit more sense that the docousin gives him an experimental serum that results in his sterility, with a side quest helping Docousin find a cure down the line. This potentially could lead to different difficulties as you could tie taking the serum with increase gains to int/str and energy increase, refusing the serum of course means slower gains and with the MC no longer being sterile that would affect sexual relationships i.e refusal unless condom is used, potential of pregnancy ( not sure how to interpret it into the story unless it's counted as a ending). Also can you please change the sex mini game, Its just not that good unless you can do precise mouse movements.
