You know that feeling, when you suddenly heard them that they've dating back then, and you keep telling yourself that 'im not bothered at all or I should not bothered about it, it's all in the past' and yet you kept thinking and being paranoid is what most every living person do and I too(it's a shameful manner but that's normal y'know).

Wait, what's dry orgasm? I don't have any idea

It is, actually. I mean ejaculation is just an end response to pleasure because of the hormones in the brain. But the human body has countless other physiological responses to pleasure except ejaculation depending on the state of your hormones and brain. This makes dry orgasm possible for some people as they can reach the peak without cumming by responding differently to pleasure like uncontrollable violent shivering,trembling, gasping or even temporarily blacking out from pleasure.
On another note, it may also mean underlying medical conditions may be the reason why it’s happening so it isn’t entirely like a great thing either.
Hope that helps!
OM. The season 2 already caught up my curiosity, I am more interested what's all about Hyesung's nightmare back then 6yrs.ago...
