If the sperm is present in our private part and we urinate will the urine kill the sperm or flush it out because I sat on a toilet seat which had semen or something like that and didn't wash my private part after sitting on the toilet seat and I just urinated and came without washing my private part. So will the urine residue in my private part kill the sperm or can the sperm go inside my body? Can it cause pregnancy? I am really worried. Please reply soon.
