I have questions I've always wanted to ask the opposite sex but too afraid to ask!
You can't know until you ask those question. So, why not fire away?
I hope these random questions wouldn't ruin my relationship.
It's best to let people tell you they are comfortable talking about some things. Or at least, gather that information if you can at first.
It will be a different situation but I hope my girl wouldn't get mad at me if I asked her certain questions.
You won't know till you ask. Why dwell on it when it is easier to ask, right?
