Because filthy people do it a lot but it is not in the Bible. I never knew how people ever thought it was good or right. It is a pagan practice people do that is not endorsed anywhere in Scripture.
You obviously didn't read what I replied to. That part was a direct answer to:
"and nowhere in the bible does it say that a woman is equal to a man at any level!"
See? Just as nowhere in the Bible does it say that a woman is equal to a man (something that a woman would want the Bible to say), also nowhere in the Bible is oral sex commanded or instructed. It is a reasonable mental leap that ANY reasonable adult would make.
To me, that is JUST another topic and means nothing to me and is JUST as valid as all others to discuss. When you have a pure heart, all things are lawful. Paul said that. I won't judge, but I will make the educated guess that those trying to use what I said there against me don't have a clear conscience.
An intelligent person will likely not quote a post unless they have something to say that is related to what was said there. So you should have read what I quoted and asked yourself how what I said related to his post. That is something you could have done on your own, exercising your own inner power and preventing you from needing to bother others. Knowledge is power.
Nowhere in the bible does it forbid oral sex, you considering it filthy and the fact you call yourself "asexual" makes me question your upbringing. Maybe you were traumatized at some point and now view sex as "filthy".
