yes you do.
during puberty you body changes
mood swings
voice lowers
(most noticeable) your penis and testicles will grow also your body will enable itself to start being able to ejaculate discharge and sperm before puberty it is impossible to have kids and you may know you should never have sex before you hit puberty for you are to young for sex (usually) all though on occasion people haven't hit puberty till there 20's
Actually if your a girl it would but for guys its not normal to
yes, if the girl has hit puberty.
yes the girl will get pregnant if sperm gets intoher vagina
No.
A guy goes through puberty just like girls. Guys develop deeper voices, and pubic hair and some other things.
Yes. If your menstrual cycle has started, it means that you are ovulating, and therefore you can get pregnant.
No
No, a girl must have her period. Men cannot produce sperm until they hit puberty. You can't get pregnant if the male has not started to ejaculate sperm. It is when the male starts puberty that he can begin to ejaculate sperm in the semen.
Keep in mind that if the male is at an age that he is still prepubescent, having sex with him is almost definitely illegal. Since guys do not mature and release sperm before the onset of puberty - technically no. HOWEVER Just because you think a guy hasn't reached that point in puberty is no guarantee that he hasn't. It is possible for a guy to get a girl pregnant even though neither one THINKS he has reached puberty. He may have started puberty and it just isn't apparent yet.
Yes she can if no protection is used and even if its the guys first time she may still come out pregnant
most guys go through a growth spurt when they are going through puberty and that happens around the age of 12-16
First of all, not all guys do. But for the guys who do, its because of hormones and his attraction towards the girl. He can't help it, especially if its during puberty.
