Not even once…If you go there, for /pol/, /v/, /fit/ or any other board on that 4chan website, then you are asking to be aroused, full of lust and fail.
Just don't bother going there anymore, it's endless erotic posting, or soft porn/ hard porn shilling, it's no use.
If you go there, you are setting yourself to fail…If you go there, you are sinning against semen retention and sexual purity.
