I believe if a lady have a sense of value she will keep herself unntil marraaige, aand guys who are in luv shld prove it by waiting until marraige for sexual intimacy unless of course they are jst in love with the girl for sex only. Premarital sex is an evidence of lust not love and lust fades with time but true love never fails.

If u are a Lady knw surely that their blessing is necessary, in fact u cant go on without bin given out by ur parents. But as a man u r expected to leave ur parent and cleave un2 ur wife. Weda or not ur parent consent to ur decision is actually immaterial.
