Curious, guys that had their first bottom, how much trouble did you have taking cock all the way in? I have been practicing with butt plug and didldo, but 3 inches is about all I can get in.
I've probably tried 8 or 10 different dildos and vibes over the years.
For dildos, I've found that my sweet spot is one that's 1.5 inches in diameter. It's big enough that it takes some time to work in, but there's almost no pain and it stretches me enough to feel absolutely amazing. I've taken some bigger ones, but I didn't enjoy them as much.
