If you have anal sex, the male ejaculates into the anus, and you hold the sperm and release it into the toilet, can it still travel down to the vagina and get you pregnant?

It was kind of hard to push the sperm out, so I would assume that none of it travelled. But what if while he pulled out that some came out and travelled down? I don't know.

If the sperm was secure into the anus and the left over in there was pushed out in the toilet, and while being pushed out and wiped off, could it travel to the vagina?
