I've recently came across this book and I accidently logged out while reading. It's about a guy who hides the fact that he has a sensitive body and he thought working out would be the cure. He encountered a guy who heard him jerking off once who appears to be his trainor and now teases him. The character's name is Param and the trainer is red-haired.

Definitely just bored. Hope someone comes by, hoping to meet Fundanshis as well cause I have too many Fujo sis, lmao. I have insta, @weirdly_inlove. Talk to me whenever you like! (。•ᴗ-)✧
Hellooo do you have a discord by any chance?
I used to, I can use it again, why?
