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.)
Flirty answer followed by real answer if actually pressed. It’s not like it’s something you reasonably have control over anyway (I don’t consider lengthening surgery reasonable, though more power to anyone that does, it ain’t my body), outside of maybe some small gains if losing weight in your pelvis area or improving your general cardiovascular health.
Not gonna come out here and say size is totally irrelevant, but there’s lots of ways to have great sex without going around bruising women’s cervixes.
