Mount War by Me and You

Asuka Kiritani called out Taichi Sakakibara, a classmate, and suddenly said, "You're bisexual, aren't you? ^^" He then claimed to be the same.

At first, Taichi denied it, but Asuka's persistent provocations led him to reveal that he was a virgin. Asuka was enjoying Taichi's reaction for fun, but when he learned that he had been with a man before, he suggested they become friends with benefits as practice until he could get a girlfriend.
