I just can not think in any other thing that he getting STDs hahaha

Why would he get an STD? These women are clearly screened and carefully selected from billions. Of course they'd be tested for anything that'd potentially harm one of the last surviving males.
Not to mention we don't know how far medical technology has advanced. They were able to cure his MS, after all, a nerve-degeneration disease. What would a few STDs matter compared to that? They might have eradicated STDs in this future, like Smallpox and Polio of today.
I have mixed feelings while reading this... first I hated everything but then I kinda like it but then again, ended hating some events, people, couples but I couldn't stop reading... I'm so fucked up.
you are normal
its normal to hate somethings and like somethings as long as you are comfortable and safe with your own boundaries.
