Having had sex with 9 men doesn't mean she cannot now be faithful to you. In my earlier years, I could number rather more than 9 - but now am married and very happily monogamous. I'd be more worried by her age than by her past. 19 is very young to really know your mind (and heart and body and soul).
Suppose you put it to her that your principles require abstinence until marriage and set a wedding date 18 months ahead. If she loves you and you her, you'll find ways to meet each other's needs continently until then. And it does give you a chance to find out if you are right for each other.
A couple of my younger-generation friends took the purity option, were engaged for two years including several camping holidays, and have now been happily married for 7 years with no sign of problems. It can be done - but it's not exactly common.
hey ,i guess you need to dump her and marry someone with whom you would not have any issues ,i am not saying having premarital sex is good or bad but the fact that you are asking this here goes to say that you are already in doubt and well marriage is a big wake up call so dont think that love will conquer it,,had you also been around it wouldnt have mattered but you have been a virgin and you know that she has done it with others ,even if she does sometyhihg in bed you wuld be thinking the whole night as to who taught her that,,so instead of killing yoursefl with this ****,,do yourslef a favor,,leave her and marry someone who you dont know had slept with 9 or 90 men..all the best
this is not a complicated problem. in fact it is the most common question (after "when will i get married?") that indian men ask on this site.
the answer is always the same, this is YOUR problem, not hers, and if you can't find a way to get over this you need to leave this girl alone. there is no guarantee that anyone will be faithful throughout all their marriage, and being a virgin or not doesn't up the odds in either direction. also, if you TRULY loved this girl you would love her enough to forgive and forget her past. if you can't do this, then you simply don't love her enough to make her a good husband. she deserves someone who accepts her completely. if this person is not you, do the right thing and forget her.
* of course God allows you to marry her. God is forgiving and loving and does not approve of judgements made by man. the bible tells us "Above all, love each other deeply, because love covers over a multitude of sins." - 1 Peter 4:8
