exactly that or he is just too perfect in everything - even in being an experienced virgin xD
Eh...that last panel though...

If they'd both been virgins, they would've taken each others' virginities, so I would say, no, Yuuma was not a virgin (unless, of course, it was translation error)
Exactly! Imagination rocks!
Hey, I don't think seme loses their virginity by being fucked in the ass. They lose virgity too when they drill their Uke. And the last panel didn't suggest that he wasn't a virgin. He just cleared it out to his friend.
Yeah, he just meant that he wouldn't need advice form the person he took the virginity. He didn't mentioned to be one himself, but he also didn't said anything that would make what I said wrong.
It depends on our imagination or maybe an extra chapter :)
If he has been in love with his best friend for a long time then he can possibly be a virgin. How did he learn a lot? Come on guys! Even a virgin has what we called imagination the more they are in love and lusting over their crush, the more they search for some creative things ONLINE.
