His finger got stuck

My man stuck his finger in my butt which was originally lubed, but he stopped moving his finger, so when I wanted to get up, there was a tug because my sphincter relaxed around his finger. He had to slide out, instead of me pulling away. Anyway, I’ve been wanting an anal plug, & a few hours ago just learned about how it functions and how our body reacts to them & I guess I can say I got a minor glimpse with his finger. He’s against me getting toys lol he says I have him to stretch me out and he can just put the tip in 🙄. 😂😂😂
