Is there a way to request for your thread to be locked?

[Mijin]

I requested for my thread to be locked due to it going way off topic and people not following the rules of it.

I'm not complaining about it being locked, I'm just wondering how you did it. Like, how did you request? Just by posting?

I reported that thread too much sexual content

How did you report the whole thread? Or did you just report individual posts? Are suggestive pictures against forum rules as long as it doesn't contain nudity? I didn't think they were.
