Yes it is safe.
No, sperm in the colon will not result in pregnancy. However, the fact that the sperm is there shows close proximity to the areas that do result in pregnancy.
Depends where the semen is, if it is inside, yes.
Sperm needs to be deposited inside the vagina during sexual intercourse for pregnancy to occur.
Yews you can and is completely safe (atleast for pregnacy since she is already on state) not for STD but u can come inside no problem.
Highly unlikely. No, typically the egg accepts only one sperm. Any sperm during or after the event will have no affect on the pregnancy. No

Unlikely but not impossible
No, sperm are required for pregnancy.
What do you mean exactly? If you mean you finish your period and then got sperm inside you and your period came back it means your pregnancy was a failure
Yes -- Sperm can live inside the body for about five days, so if the pill is stopped during that time, pregnancy can occur. Also, no pill is perfect! There is a small chance of pregnancy regardless.
No, once the egg is fertilized with a sperm and his DNA it can not be changed. The uterus closed and nothing can in in if you are referring to sex during pregnancy.
Pregnancy, under the right conditions.
