What are the consequences...?

Question

ok my friend told me that if you can't do the splits but you try and somehow fall into them you pop this thing (for girls) inside of you or something. and it makes you lose your virginity and even if you tell someone you're a virgin but after marriage you have s*x they can tell your "not" even tho you never did it. so is this true? and what are the consequences then? and if you stretch every day for 3 weeks can you do the splits without popping this thing?
