You are 101% right in your mind as this will keep your purity intact and you will get in to very neat and clean life with clea purpose.Those who thinks that human are bound to react the way animanl react i think they should admit this fact that they are worse then animal who has not given intellect by mother nature to distinguish between pure and impure relations.
You should ask your friend that when it's just like animal then i she hides her sex life why can't she tell her encounter in open to every one why she wants to be on virginity side i.e by way o f showing that they have not done anything.
You would notice that such kind of person are worse then animal as they don't pretend what they don't do.But human has a habit of showing what they are not that's what gives clear thought in deciding what 's wrong and what's right.
So just be with your thought and later on in coming years you will see these people regretting their actions impure actions.
