Hera saathi. First off, anybody else would laugh this matter off. I would have done the same too but I know its anything but funny to you right now. The thing is, would any girl have said yes I've had sex before when you asked them? No. These are very intimate problems and I know it must be bothering you real deep which is why you are so publicly asking for help but you need to understand that arrange marriage itself is a very complicated way to start life. I know you must have had fantasies and visions about how beautiful your 'first time' would be and that all of it is gone because she's not a virgin but stop killing yourself over it. I know since you are a virgin, you were looking for the same and which is quite corky but reasonable nonetheless since you haven't done it. Saathi, aba sex paap ta haina. Usle dhaatyo ta ke garney? Bihey bhai sakyo haina? Timi euta raamro khaandan ko, most probably brahmin pariwaar ko keta hola. Timlai dhoka bhayeko jasto lagna sakcha tara yo kuraharu aba saamanya bhaisakyo ra virgin nabhayera kasailai hate garnu cultural haina childish and extremist sunincha. Find out if you love her, find out if she's bothered because you are feeling uneasy, find out about her, let her be, maybe ask her if it bothers you that much, try to be gentle, or even make love more, ask her whats bothering you. Basically, find out if you can fall in love with this chick and spend your life with her which is a bigger deal. If this felt like a deal and a favour or a compromise more than love then stop now because you don't want to start your life with regret and hate. Bholi baccha hola, keke hola ani ke garney? Dont hate her for what was in her past, try to see if the present is worth it. If it bothers you that much then you should be able to ask her, if you cant then its not love.
