I would be annoyed if she said she wanted to wait 'til marriage, because that could take forever in our current state, unless we move to somewhere where it would be acknowledged.
If not, and she's just nervous or uncomfortable or whatever, I would say something cheesy, like: "It's ok, bby, I can wait 'til you're ready." emotion_kirakira
More than likely, though, I'll end up dating a non-virgin and be the nervous one in the relationship. Just the thought of undressing in front of someone else creeps me the ******** out.
