If you haven't got your menstruation at 17-18 you should go see a doctor. Up til then it's normal.
Semen can't really effect menstruation, this is because menstruation is controlled by the hormones in a woman's body - the only time semen can effect menstruation is if it results in pregnancy. Semen can however soften the cervix which can help induce a late period.
Menstruation typically begins in either late Tanner stage II or early Tanner stage III of puberty.
