Is there something wrong with not wanting to lose my virginity to someone I've dated for a week?

You should definitely stay true to your virtues and don't let him walk all over you! Honestly, if he's pushing you that bad for after only a week hes not worth it, he's also trying to make it seem like there's something wrong with you (obviously, since youre asking if there's something wrong with you) and manipulating you so you will have with him, this dude's only going to end up screwing with you psychologically in the long run, he doesnt seem like he'd be the best bf, in my opinion! you could do better!
