Yes; it is unlikely but possible.
No she can not get pregnant from semen on her hand.
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.
Regardless of how fresh semen is inserted into the vagina you risk pregnancy. Even with a hand.
One, are you a girl, two if not then sit back and let her give you a hand job :D haha
it takes sperm and a egg to get pregnant and none of those can be find in your colon so no.
those two functions can't happen at the same time because: A: the urethra is too small and would rupture and B: your body won't let you.
Unlikely but not impossible.
no. But you must be very careful not to get any sperm on your hands and to touch your genitals with the same hand (which has the sperm on it) No. With penis girl can't. With ejaculation of semen it may be possible
He either likes you more than friends or he is a pervert that touches every girl by body language.

It really all depends on which hand you are using to touch the semen with and which hand you are wiping off. Maybe you were eating pizza and still had some sauce on the hand without the semen on it, then you just wiped off the pizza sauce instead of the semen that you've just touched...while eating the pizza. Overall, my understanding is that if semen were to enter a vagina then there is a possibility of pregnancy. You're welcome.
When you hand touches the hot handle of a pot. When you touch an ice cube and it melts in your hand. When the spoon touches hot water and the spoon gets hot. When the spoon touches cold ice cream and the ice cream melts.
