Pre-Marital footsie is a SIN.
You blew it because you were too timid, and have issues about sex. Or she just enjoyed the attention. How else do you explain your rejection by someone who had initially shown interest, albeit toe-based? Oh, you rationalize that it's because her dads a pastor and she's not allowed to date? Sorry, that's not it, though she gave you a big clue about with her comment about her bubbly personality leading a lot of men on.
Now you're 'in love' with her and will no doubt ignore any advice that says to stop thinking of her as an innocent little flower who needs your protection and start treating her as a ripe young muffin in need of a good f*cking.
My advice is to forget this christianity nonsense and stop being ashamed of your male lust. Or fuel your hopeless oneitis with delusions of her angelness and watch as she finds a bad-boy to 'save.'
