Spoiler.
They did speep together and not just one time.

Jun - uke, married once, a kid.
Ei - seme, slept with a friend of them (Angelo) in highschool, using him as replacement for Jun.
Jun saw Angelo coming out of Ei's room after sex.
so disappointed ╥﹏╥

I don't think Ei would be uke for anyone
Wait!????? What?!!!!!!
Jin, WTF!? Why do you think EI slept with Angelo!!!??? Love the update but hate the cliffhanger at the end
