So that wasn't normal, and I have the assumption the MC is an idiot.
First of all not all men only think sleep, eat, sex, is normal.
That could get boring real fast?
And yes, you CAN get sick of sex if you have it enough.
Even for the sake of "comedy", this is not funny to me personally but if anybody else does then that's nice I guess.
Sorry for seeming negative, but this chapter was kinda stupid...
This manga will probably be another sex sells manga that's only redeeming feature is ecchi/erotic content.
Dropped~
