it's not always the physical things that can be considered a pleasure, as someone who actually tried it, it's more like a pleasure for seeing them getting pleasured, though, in this manwha they had only showed the typical "bottom" and "top" dynamic but other GL manwhas shows smuts that has "switching" on it, it's when the bottom gets to top then the top gets to be the bottom. though, mostly manwhas shows stone hard top and pillow princess bottoms.

Guys this is my first time reading gl and Im around ch 20 and wanna know why only the bottom is getting pleasured like I mean how do I explain this
See for bl they both get pleasure because they have dicks but the girls here aren't even using a dildo
So do they use it in the later chapters? Does the top also gets pleasured by the bottom sometimes?
