I’m a female who can’t quite take a large penis. I was recently with a guy who was super respectful, took my cues, and did everything right, but I ultimately couldn’t take all of him without hurting. I was hesitant to get on top, because I figured that, unless I kept holding myself up, gravity would do it’s job and when I get on him his penis would go all the way in me. I decided to at least try it, so I could be more in charge. Turns out, I was able to easily take all of him. A few times I asked him if he was still in me. I couldn’t tell if he was in me or not. Anyway point is, why the hell was being on top so dramatically different? Why was it so easy to take his larger penis when I was on him, but I barely could take it when I was in various bottom positions?

Edit: Why did I think this would be a straight forward discussion about the mechanics of sex? 🤦‍♀️ Please don’t message me propositions. I’m just looking for answers and I will only speak about the technicalities of what I’m asking.
