Why do girls lie about having had boyfriends ?

The topic has taken a diff turn..u missed that.. =) there's no way lying is acceptable. A girl usually lies to be accepted by the guy.. there are plenty of men out there who claim to have never been with anyone and later to come to know that they lied throughout!

I am actually replying to Jimmy here who finds such girls "filthy" etc.. that girl committed a sin, she asked Allah for forgiveness and Allah forgives everyone that repents with sincerity..
