Welcome to yaoi land. I'd just avoid some of the yaoi doujinshi's like this as much as possible if you don't want to see other things like this, they contain most of this that are sometimes traumatic (´-﹏-`;), you can put an x button on the doujinshi genres to avoid seeing other things like this. But if you wanna give yaoi another go, I'd recommend checking the ratings and comments before reading to avoid any further trauma some yaoi gives. Here are some safe recommendations.
Shounen Ai:
1. A Paramour
2. Who Can Define Popularity?
3. Karasugaoka Don't be shy!!
4. 19 Days
5. Timeless melody
But if you want a bit of some spicy bed scenes included (◠‿・), here are some Yaoi's i've read:
Yaoi:
1. Blood Link
2. Hosik's Story
3. Dangerous Convenience Store
4. On of Off
5. Wolf In The House
You just have to be careful most of the time to avoid seeing other things like this (|||^ω^)
I LOVE WHO CAN DEFINE POPULARITY!!! I'd also recommend:
-The Best Smell (shounen ai)
-Mo Dao Zu Shi (shounen ai)
-At the End of the Road (shounen ai)
-Never Understand (shounen ai)
-All of You (shounen ai)
-Banana Fish (shounen ai)
-Mother's Spirit (yaoi)
-Heaven's Official Blessing (shounen ai)
-Half of me (shounen ai)
-Monster and Ghost (shounen ai)
-Cherry Blossoms After Winter (yaoi)
-Between the Stars (shounen ai)
-Tale of the Yellow Dragon (yaoi)

I’ve never read yaoi bc I read yuri but everyone says yaoi is good but.. I don’t know how I feel about my favorite superhero getting fucked..
