Genuinely asking. Is anal sex has same feeling like constipation?

TRIGGER WARNING: If you feel grossed of this topic just pass. I am genuinely asking because I never had the experience.

I suffered constipation these days due to stupid medicine I have to take. Every time I wanna take a loo, I feel very intense feeling and it very hurtful. I just gonna imagine that brown thing as a cutie dick (just to reduce painful feel like psychological thing, I dunno too many vocabulary).

Can a dick fit enough get into the hole? Can the hole flex even bigger?

Alright. I finished my question. Look. I know as stupid as it sounds that is why I am asking.

Anyway, thank you for responding my question. You guys are awesome. Happy Friday y'all.
