I would not disabuse your young relatives of the notion that you can be trusted to tell the truth, but the idea of the existence of Santa Claus would not come from me. More pertinently, I do not fuck children. That's repugnant, illegal and immoral. So, I fully expect that anyone I would reject after we undressed would be a grown man, and could handle a gentle presentation of facts. For better or worse, dicks do not grow on foreheads, so it's pretty impossible to know whether or not I like it until a fairly vulnerable stage. But I do unto others as I would have them do unto me. I don't want anyone laying with me who doesn't really want to. I'd rather be told it isn't working out, the second it isn't working out.
And maybe you don't get this because you are not a woman, but I am not letting anyone put anything inside my body if I do not like it. I can be nice about it (I don't think the one dude I rejected partially because of his weirdly shaped, tiny dick would complain too loudly that my rejection consisted of giving him orgasms until he fell asleep and then vanishing without a trace). I would never be unnecessarily unkind. But unless a whole lot of other things are just perfect, and I'm talking about things I might let go of with another man, like eye color, or his opinion of Rush Limbaugh, there is a certain size range above which or below which my experience says I probably wouldn't like, and I would find a way out of the encounter if he wasn't so phenomenal otherwise that I wanted to try it out. But by phenomenal otherwise, I really do mean the stuff of legends.
I'm not conceited. I just want to only share my body with those who are really totally into me, and as a courtesy, I would never let anyone waste his time with me if I wasn't all about him. So yes. If I ever find myself dating or sleeping around again, and I stumble across the rare dick I do not like (only been one in nearly two decades) I won't sneak out like a coward as I did last time. I might thank him for a lovely evening, tell him I can't go through with it, and bounce. If he presses and must have a reason, I will let him know diplomatically I don't like his penis. It won't be the end of the world. Just like it wasn't the end of the world when a man undressed me and then told me he was disappointed that my breasts were not fake, which is his preference. He also expressed shock and disappointment over the shape of my vulva. I was disappointed, but I got over it, and he was blunt and forthright, but not actually unkind.
Before I go, I have to say I wonder how you missed the last part of the same paragraph from which came those sentences to which you took offense. I hope most people know that context is everything. Let's reprise my idea of one honest, respectful way to exit when the issue is a mismatched size, whether too big or too small:
