BUTT STUFF: Does it hurt?
Let's get real: The anus is a pretty small opening, and it lacks some of the natural stretchiness and wetness of the vagina. So if you wanna get down from behind, eve recommends starting small, and slow, and with lots of lube.
The first time you feel a finger up your backdoor, you may feel pain or even like you have to poop (don't worry, you won't!). If it's hurting, try using more lube or starting with an even smaller object. But if it keeps hurting and you're not into it, don't feel any pressure to continue! The whole point of sex is to feel fantastic, so if it's not working for you, stop!
Pro tip: If you're going for anal play, it's a good idea to cut your nails. That skin is sensitive.
