Penis issue. I am 184 cm, please help.

I just got to know that i have little too huge penis size it is around 23-24 cm i dontknow i am too scared that it might be some sort of cancer, i dontknow of its normal or just something serious issue, this afternoon i had vaginal sex for the first time, and i have hurt my partner bad, she was having so much pain, and i google searched it, which i shouldn't have and now i am scared, she is fine though, what should i do should i consult a doctor physically or an online consultation would be fine for both of us, i cant step outside of house due to my area being an containment zone, plus since i remember as a kid my penis has been normal, i never had pain or anything except if i get random erection while wearing jeans it does hurt, but i thought of it being normal size, is it something related to height, but i am not even that tall i am 184 cm, please help.
