i don't think they had sex while he was not transformed in the bathroom. until the last chapter they didn't do it while he was in his normal form so i guess that's what it means by losing virginity
He totally did with that poder brother guy after turning back into His normal self!! He even complained it hurt without the transformation!!! And afterwards he complained the guy came inside and he felt gross!!!
So basically a man losing their virginity involves Inter pese where they r the people inserting it in. With the older brother guy etc it was only anal sex!
Intercourse*
Wait, didn’t he already lose his Virginity in chapter 3? I’m at a total loss, please explain...
