I don't care at all that I wipe incorrectly
Why are you telling me this? Why do you not want to wipe correctly?
It's just a stupid detail, so I don't care.
You need to learn how to wipe correctly. It is unhygenic not  to do so.
I don't need to learn, it's not like I have a micro-penis.
I don't think having a micro-penis relates to learning how to wipe. I think it's best to learn how to clean yourself better, because a lot of disease and irritation can come from improper cleaning. Wouldn't you want to be intimate with others, as well without being dirty?
