Should girls be virgin before marriage? Or not to sleep around a lot !!

That is up to them to decide. Not you, not me, not some made up sky father.

Mohammad, it never occurred to me to ask. In my country women have minds of their own. Like men, they make their own choices.

I would prefer experience over fumbling virginity any time. My ego isn't so fragile that I need to believe that I'm the only man a woman has ever known. Sheesh!

There's a line from "The King and I" that probably covers your situation. "A flock of sheep and you the only ram? No wonder you're the wonder of Siam."

I wouldn't add any "Must" into it. It's totally up to the person, it's a very personal decision by any different reasons.& also  losing virginity can happen by thousand of reasons that we might not understand.

It could be rape, it could be followed by a mistake like being drunk, it could be youth, pressure of hormones & devilish of a guy. Or a complete self choice.

Morality aside, why not phrase the question this way:  Do women prefer an experienced lover or would they prefer a "newbie" that they can learn with or teach?

Before marriage, I have to do my responsibilities such a finishing school, looking for job to help support my younger siblings' education, to help my family in financial matters, to achieve my dreams such as to have MBA, own business, study pastry, among others. And having pre-marital sex is not in my list.

Achieving personal dreams and goals in life before marriage will make me feel complete and successful, making my single life amazing and worthy. Marriage is my last resort.

And yes, I value virginity before marriage.

I think girls who are serious and have many goals in life will put career first without being interrupted by a man. So they able to remain virgin before marriage.

Depends on WHY.

The original reason for women to be virgins before marriage, was simply because they were viewed as little more than property.  So if they weren't a virgin - it was viewed as "illegal" use of someone else's property.

Since we have (hopefully) moved beyond thinking of women as chattel ... The best reasons for staying virgins (for both male and female) are STDs and "unwanted" children.

Depending on your definition of "a lot" there could be an issue. If a person, man or woman, sleeps around a lot as in one night stands and such, with no regard for a real relationship, then I think they are looking for something in the wrong way and they need to deal with that before marrying or committing to anyone. If you mean they slept with 3 or 4 people but were in a serious relationship at the time, I don't think that is an issue.
