Well, when I was 5, my friend had this idea that we stick our penises in each others asses. I complied. I did not enjoy, nor deteste the experience. Neither of us knew what we were doing. So technically, I lost my virginity to a 5 year old boy when I was 5.
But the really funny part is..... my friend's brother was also present and they also fucked each other. So they will have to live the rest of their lives knowing that when they were kids, they fucked each other in the ass. LOL!!!!!!!!!!!!!!!!!!!!!!! Then again, I remained best friends with this guy until I was 17..... and every once in a while I would think to myself.... we fucked each other in the ass. None of us ever spoke of the incident, though.
