There's also a button at the top of the message section that allows you to create a link. Just like on the reply to posts. It's a blue circle with a chain link at the bottom. That should allow you to create a link.
My Literotica Submissions
Gentlemen may prefer blondes, but it takes a real man to handle a redhead.
I came to Literotica for the Eros. I stay for the Agape (LakeSailer_MI, 2013).
Random dicks don't do a damned thing for me.
I don't care how thick, how long, or how thick and long it is.
If I don't first like the man, his dick is just another dick.
I'm a nurse; I've seen more dicks than a prostitute.
