My boyfriend has been trying to do butt stuff and last night we were orally pleasing each other at the same time (69) & he straight stuck his finger in my butt. I am clean down there but I still feel uncomfortable with it but want to try butt stuff. I'm shaved and everything. When he did that I got the feeling I had to poop then he pulled it out and it went away. Does it always feel like that?? Just need advice to make this easier on me.    Lmao  HELPPP.
