A pseudonym does not make you a different person, nor does it give you license to engage with others as if you were. It is wholly disingenuous to take advantage of another person's trust and infringe on consent given to someone who is not you.
Now, there's been this misconception going around saying, 'women write erotica, men write porn'. The basis for this concept is, as you can imagine, when women write, they do so using emotions, romance, and seduction. Whereas men only write slutty women performing sex acts from start to finish, just as you might see in porn. While this may be true for a lot of erotica writers, it's the wrong state of mind to have when choosing the next author to read. But the concept doesn't end there either.
