Yo. Im trying to find the title for this manga but its about two ukes who have sex with each other i remeber to decide who would be the seme they compared whos penis is the largest lol i think the seme had long hair. This was like a year ago when i first started reading it so i pushed it off and didn't finish it but now i really want to read it again so if you know it or read it please tell me

Is it Hana to usagi?

Moved to Yaoi/Yuri.

No, but seems intersting

Is it this one?
The battle of the wolves
Thsi one has a similar theme- Ore-tachi no kijou jitai!! (they both are fighting to be the top tho)

Minami Haruka has alot of manga like that..
Although it's mostly shotacon..
Also Boku no Pick I guess?? Although it's probably not the one.

Also, do you know where to ask questions like this? I'm new to this website so I don't really know how it works 😕

To ask a question open the right forum (if your question is related to yaoi/yuri then in this forum, or if it's a general manga then in "I'm looking for" forum).
You can start a new topic by clicking "New topic" on the top right of the forum. 🙂
Hope this helps.
Also you can directly link manga/ authors by using the codes povided ( manga name ) without the space.
