to be fair, there is some level of difference between refusing to answer a question yourself (either actively as you have, or passively by just not responding and moving on to another thread instead), and doing so while also deriding others as tactless and cruel for choosing to respond themselves. perhaps it is less these others trying to peer pressure you into answering yourself and more defending either their own inclination to respond or defending those that have done so.
also, there's nothing in the OP saying that a smaller than average or average sized penis is a BAD thing worthy of ridicule, nor was it saying anyone had to give someone's name or discuss the context. it merely asked for the measurements. anything added beyond that would be the respondents' choice. in some cases, it might actually be a GOOD thing...there are plenty of stories of guys with smaller equipment who know how to use it quite well or make up for it in other regards (as the discussion threads about larger men have revealed some problems those sizes have, or the men's lack of ability in its usage). mentioning those things as well could help alleviate some of the insecurity that is often associated with being less endowed, don't you think? just an open and honest discussion...nothing wrong with that.
