YES , a girl can get pregnant whether it is first, second or a hundredth time to have sex. As long as this sex is unprotected or wrongfully protected [where a condom has been used the wrong way] and this same girl is not using any other control measures like pills, she may get pregnant. The probability is highest around the time of ovulation (when the egg is released).
Should the man place his penis in the vagina and he ejaculates sperms in the woman after she has ovulated or when about to ovulate, even if it is first time to have sex, she can get pregnant
