Can't agree with you this time, my friend.
If we both smoke cannabis, we'll just end up watching videos and eating munchies glued to the couch all night until we pass out on each other's shoulder. I prefer to be awake for sex... I prefer SHE be awake for sex too! Hahaha
Ahegao is childish, like a young girl who didn't get her own way then makes a sour face, sticks her tongue out as far as she possibly can, looks cross eyed and makes a noise that sounds something like...
Nnnnnnnnnnnnnnnnnnnnnyaaaaa!
NOT sexy, just childish.
I am all for creative adult role play but ahegao has no redeeming value to an adult. I am not into loli or shota content either as that only serves to sexualize minors and as a father and grandfather I detest that sort of behavior. Ahegao gets thrown in the same rubbish fire for a similar reason... it only reminds me of a young girl who heard NO to something she wanted and pitched a hissy fit. I only have one thing to say to that little girl. You can't always get what you want.
If a woman you are with ever makes an ahegao face when she is with you I can guarantee that she is faking it out of some misguided effort thinking you enjoy that perverted fetish. Ahegao is extreme and fake. It doesn't look sexy or attractive on anyone, ever. And that's all I have to say about that...
