So i didnt cum, right??

i was having sex and i had an erection throughout the whole time i was with her. i was for certain i didnt cum. i felt her wet, but i did not have an orgasm/ the feeling of cumming. she told she had an orgasm, but it was cuz i was rubbing her vagina when she was on top of me. so yesterday and today i decide to "test" masturbate, with and without lube, and i felt the orgasm for both and i felt the need to cum and i did. then today, i searched "can girls feel a guy cum inside of them" and i read that sometimes they can feel, but they can feel the throbbing/pulsating/muscle contracting of the penis when the male is about to cum. so i talked to the girl who i had sex with it and i asked her if she felt anything unnatural when i was inside of her and she said no. and i asked if she felt my penis throbbing/pulsating and she said no. so now im thinking that i didnt cum when i was having sex with her, right?
