[Request] of a gay dragon comic

It’s a comic where two dragons are in a cave and they are talking, and the big one is stopping, the little one didn’t notice and stumbled into his rear. Noticing that he’s pal has a slit, thinking it’s a girl but nope
I completely forgot the artist name and comic title, can someone help me ?
If I’m correct there was one little dragon that was green and the other one red
