I wrote a post today to the following forum: http://www.lpsg.org/adult-websites/31416-initial-penetration-porn.html It the thread deals with the way porn gives little attention to the act of penetration itself, and as we know, it can take a lot longer with big cocks than is shown in porn. The act of penetration is very erotic in itself. In my post, I describe self-lubricating sex between guys. I'd like to know if others have experienced the same thing. Straight sex, it goes without saying, usually doesn't need additional lube or am I wrong?
