Has any one done ?

I have done it w my gf before a few times. Just remember to use a lot of water based lube, tell him to take it really slow, and you have to relax as much as possible. The more you tense up, the more it will hurt you and make it harder for him to get it in. Which isn't pleasant for anyone involved. I would advise using a condom,too bc it does have fecal matter up there obviously. But that is your choice. By the way, I RARELY hear of people defecating during , so don't worry
