This reads like a joke question, I know, but I actually mean it.
Are you supposed to answer this sort of suggestive question with honesty? Or is this generally meant to be answered in coy and or affirmation? Because I don’t want to ruin the mood but I also don’t want to unwittingly spoil her expectations. (FYI, I’m average sized.)
You tell her you hope that she’s not scared too easily and do it with a straight face. Then, say no more on the subject. She’ll be too intrigued at the meaning of it to hold back the curiosity. Then it’s too late. It’s just a penis.
