vyrhoci's Things

Can someone tell me if this is a thing:

In some Yaoi manga I've read, most commonly Japanese, there's this thing where the characters are saying some reference to or connected to a cat or dog, then that would be their position in bed when the sexy time comes on. Cat meaning a bottom and Dog as the top (I've read in a manga before that this is the distinction for top or bottom in japan. xD)

I just recently noticed this happening and now I'm curious if some how, it's present in a lot of yaoi...

Sorry, it's something so simple but it's just so funny that the authors would insert that clue before the sexy time. xD

I was reading this part: http://www.mangago.me/read-manga/junketsu_drop/an/junketsu-drop-chapter-2.html/14/

The character was nonchalant about it so I wonder how everyone else are.

Personally, I found out about it when I had this crush on a classmate who's cute and handsome. This was when I was in Kindergarten (6yrs old)... It didn't freak me out but rather I thought it was something normal. Like, I thought everyone else knew about it just like how everyone just know that a girl likes a boy or something like that. I thought that way until I was 10 yrs old when my classmates teased me for being "too girly and weak". That's also when I realized everyone makes fun of and hates gay people.

P.S. I still have a crush on him though even now. We've been classmates and/or schoolmates through grade school, highschool, and college, seriously. xD

I'm feeling philosophical because of that story() and as a topic, I wanna know what everyone here(those who reads manga) thinks about death. Some would usually say it's scary, others would welcome it, and there are some that doesn't think about it much. I have my own thoughts too, but I wanna know the thoughts of those who reads.
