No.
Yes.
If the sperm is fresh yes. If the sperm is old no.
Highly unlikely
Your concern is somewhat justified, in that sperm that comes in contact with the outside of your Vagina can travel the extra distance and lead to pregnancy. The specific answer to your question about a bathtub is that sperm will burst when exposed to water, so if you fill your bathtub before adding any bath soaps, you'll be safe.
if you're having your period, you probably aren't pregnant. if you had sex and then had your period, then all the sperm would be washed out of your uterus with your period. so you're not pregnant. mabye but you wouldn't be pregnant any more
No. If you are pregnant, swallowed sperm will not affect the baby. If you are not pregnant, swallowing sperm will not make you pregnant.
No; sperm must enter the vagina to get pregnant.
Swallowing sperm will not get you pregnant. The stomach acids will kill any living sperm. You can only get pregnant if sperm makes contact with an egg.
No, you can't. This is an awkward question, but, you did not let the sperm "settle" itself too much. Therefore, it couldn't get it to make a baby.
human sperm cannot get a cow pregnant. The only species humans can get pregnant with their sperm is another human.
on the vagina and washed off, I doubt it. Inside the vagina is what it takes.
Yes.
