Nevermind that. Go to the doctor.
Whatever causes stabbing pains needs to address urgently.
It is certainly not desirable, but can often occur due to deep penetration.
No. For pregnancy to occur there needs to be sperm.
Yeah if those panties touch her vagina. And those sperm get inside her vagina and impregnate her.
Only if your ejaculate shoots all the way to another woman's vagina, then no.
It is very unlikely. If no semen entered the vagina, there can be no pregnancy. A little slippage is fairly normal.
No. Unless by "grapefruit", you mean "a man ejaculating into a woman's vagina", in which case the answer is yes.
If you have fresh semen on your finger and inserts it inside her vagina, yes then she can get pregnant.
yes
It is a common myth that you cannot get pregnant if the penis does not enter the vagina. Ejaculating (or even the "pre-ejaculate" secretions) in the area of the vaginal opening can cause pregnancy. The semen must enter the vagina so other touching that does not result in this cannot cause pregnancy (but can cause some sexually transmitted diseases).
on the vagina and washed off, I doubt it. Inside the vagina is what it takes.
No, the only way for a woman to get pregnant is for semen to enter the vagina, unless you ejaculate on your hand and put in in her vagina, she will not get pregnant.
Yes, either way you slice it, its sperm entering the vagina, which can possibly fertilize and cause pregnancy.
No but it might feel that way if she is more swollen down there due to the extra blood increase.
