Penis penetrate vagina

An unbridgeable gap in understanding. But we asked a bunch of straight men to be as descriptive as possible when telling us what it actually feels like to put their penis in a vagina, so we can all get a little closer to understanding. All names have been changed, because few men want to publicly declare what sex feels like on the internet. Everything spent, but too weak to just roll over.
