Cum ?

It really confuses me when people come on here and say “idk if he pulled out in time” or “idk if he came in me he says he didnt or doesnt think he did” like ? 😂 can you not tell if he had an orgasm? Can he not tell? Does the cum not drip out of you when you stand up? No hate im just so confused when people come up here with those posts cause i have a shit ton of cum dripping out if my SO does, so its def noticeable for me and if i cant tell if he had on orgasm he just tells me if i ask 🤷🏻‍♀️
