A 13-year-old boy absolutely CAN impregnate a girl. Use condoms!
No, they cannot because girls cannot get each other pregnant. If you are asking whether a 13 year old can get pregnant by a thirteen year old boy, then the answer is 'yes'. If he is producing sperm and she is producing eggs and they have sex, it is possible for her to get pregnant.
nope go 4 it lol
No because you mite have seen the 13 year old have a child with an 18 year old
Yes, it is possible (depending on how developed the girl is, of course), for an 11-year-old boy to get a 13-year-old girl pregnant.
yes, it's possible in nature. not illegal, but probably a bad idea
Not at 13, if it is a boy, he must be 18, a girl then she has to be 16 or 17 and pregnant (in certain states).
