Finally found the manga
http://www.mangago.zone/read-manga/im_the_main_character_of_a_harem_manga_but_im_gay_so_every_day_is_hell_for_me/
And my idea was the typical “I got summoned to another world” in it the Mc made a hero party with girls who are dumbly in love with him and he finds that annoying and tries many ways to kill- uh i mean cut them off but the girls are always saved by the timely intervention of a hot guy who the MC tries to flirt with but always get cockblock by the girls. So when it is time to defeat the demon king, he faked his death whil forcing the DK in a master slave contract and MC be came the new DK and start put his conquest of creating an all male harem. He some what succeeded but its was hard because he is still being cockblock by girls. The only time he managed to do the deed is with the original DK right after the master slave contract. Oh and the MC is the seme cause i am sick of a uke point of view where he complains about his tragedies and there are way to much MC uke in novels. I gave up on the idea cause of class and i cant really right comedy.
A harem protagonist surrounded by beautiful girls except the dude is gay and falls in love with the side-bro.
No matter what he does he's stuck doing typical harem tropes (e.g trips and accidentally gropes a girl's boobs, the guy gets beat up by the tsundere girl because of a misunderstanding) and the poor guy just wants to have a happy bromance with his friend.
