My apologies if this is a repeat question. I couldn't find any guidance on this topic. While reading the forums I frequently see abbreviations or acronyms such as P for porn, M for masturbation, S for sex, etc... Is this preferred or a rule? I understand it's more efficient and quicker to type PMO than porn/masturbation/orgasm, but some members seem to use it a lot. I've got a lot stuffed in my head already. I just need to know if I have to learn a new language to post here.
