You said that you wouldn't marry any female who you had sex with, prior to marriage. That means that 1) you will only marry a virgin ( lots of luck with both of those things! LOL ), or 2) that you will marry a female who has engaged in sexual congress with someone else, but not YOU, prior to marrying you. Since, from all of your posts, I doubt that #2 is true, though it is the only other logical choice, given your previous statements.
Neither reason, nor logic is your forte.
