Of course, and if the person (man/woman) is truly in love with you, he or she would be willing to wait.

Marriage is sort of a confirmation of your love to your partner. Some people may want to seal their love with printed words, a marriage certificate. Having sex after marriage is considered safer, as to before marriage. Since marriage is a serious business, being bound to your partner for eternity, wouldn't you contemplate the what-ifs of a marriage? Ex: What if it won't work out? What if he/she cheats on me? Marriage is hardly something you would jump into before thinking through and through. If you truly love that person and you married him/her, wouldn't it be much more memorable to know that you lost your virginity to him/her, rather than some person that you barely know?

Besides that,staying a virgin until getting married is also considered a safer route, since we all know sex can lead to babies if birth control isn't used, or it failed. If you had sex before marriage and had a baby, would it be likelier that your partner would take care of both of you or would he/she take off after acknowledging the fact? As I've said before, marriage is thought through seriously and the consequences were weighed, so if you do have a baby after marriage (intentionally/unintentionally), your spouse would take care of both of you.
