No, he was topping his seme, that's why he asked his seme if it's okay
He already bottomed by his seme several times so he shouldn't be bothered to ask about it. You can see that the sex scene when he's 'taking his virginity' isn't really sexy, it's because his seme isn't made for bottoming and the uke isn't made for topping (the author doesn't want to make the reader like the reverse sex since it'll only happen once) So it was just shown slightly. The uke was topping to get rid of his dick virginity
I thought he already lost his virginity when that brother raped him in the car on chapter 3/2
