Depends on what you mean by a guy's discharge ! If you mean his ejaculation of semen and sperm than yes she can. If she want's to stay away from pregnancy then she should stop having sex with the guy and educate herself on sex and the chances of getting pregnant before she begins again.
Penile discharge.
No.
No
Yes she can if no protection is used and even if its the guys first time she may still come out pregnant
yes
Satisfaction on the woman's part is not a requirement for pregnancy.
if you are pregnant you miss your period
yes,unless you don't have a heart of love for that girl but take this advice,if you are not matured enough don't get a girl pregnant. If what you mean is, can they tell when they are having sex with a girl, if it got her pregnant that particular time, the answer is no.
Guys can never have babies despite what you may hear in the media; so a guy can not get another guy pregnant. Bisexual means the guy likes both guys and girls and he can get the girl pregnant.
Having vaginal discharge does not prevent you from getting pregnant. It will not expel the sperm. It is not a way to determine whether or not you are pregnant. You can have discharge at any time, pregnant or not.
yes the girl will get pregnant if sperm gets intoher vagina
No, we do not.
