I dont know if this is the right place to ask this and if I should take this post down, let me know and I will. This community has just been so kind and helpful that I felt most comfortable asking here.

I really, REALLY want to do DP. I love anal, and that part is no issue. But it's like as soon as a cock/dildo is in one of my holes, I cannot fit more than two fingers in the other hole comfortably. It's just too tight and I feel like I can warm up all day and it still is just too tight to fit one in both holes at the same time. I can do it interchangeably, so my boyfriend will stick his cock in my pussy and then pull out and put a dildo in my ass. No problem. Same time? Feels impossible. Is this just something that needs training or maybe some people are built different downthere so it's just not as easy? If I have a buttplug in my ass that is bigger than the smallest size, it will either pop out of my ass when he sticks his cock in my pussy or it will hurt.

Does anyone have experience with this? Any advice is appreciated! Thank you!
