No. For pregnancy to occur there needs to be sperm.
Pregnancy
Yeah if those panties touch her vagina. And those sperm get inside her vagina and impregnate her.
yes, be careful, expecially as periods in young women are more irregular...anything inserted in the vagina with semen on it could potentially cause a pregnancy
Only if your ejaculate shoots all the way to another woman's vagina, then no.
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.
It is very unlikely. If no semen entered the vagina, there can be no pregnancy. A little slippage is fairly normal.
As far as i have researched other than STRESS, pregnancy, injury and infections...Sex does not affect your periods.
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).
The truth is licking the clitoris with man's moist tongue can cause tingling sensation for woman. After which, sucking the entire opening with man's lips for added satisfaction.
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.
on the vagina and washed off, I doubt it. Inside the vagina is what it takes.
