Well, for starters, the OP says "ladies and gentlemen", so no matter what was expected, that statement opened it to everyone, and as has been pointed out, the majority of members, are men. So, when open to "all", follow the percentages. It shouldn't be a mystery why so many men respond to an equally applicable topic. If the topic was more specifically female oriented (Ladies, have you ever noticed that your vagina...), then I could see more validity to the above points.

The "women's section" issue... I've seen this complaint many times, but to be fair, most people don't really pay attention to where a post is posted, with some exceptions, on first glance. I rarely go into forums, to pick the threads that I'm going to read. I typically just look at the "Latest Threads/Posts" sidebars, and pick threads according to the thread title. It's only when something in the thread causes me to start scrutinizing the post, that I THEN look up and take notice of where it's posted.

Again, being on a Large Penis site, and asking both "ladies and gentlemen" about large cock experiences, and being that there are far more men looking at sexually oriented sites in general, no one could have seriously expected "mainly women to respond".
