I think a lot of (most maybe) members of LPSG are here because they are fascinated by huge cocks not because they need support for them. I'm not here because I need support for my slightly bigger than average cock, I joined seven years ago because the idea of reading about what it's like to own and be fucked by a huge one just turned me on. Strangely, in those seven years (my god, is it really that long?) since I joined I've come to realise that mine is big enough and I have no insecurities about my size. In fact I'm very confident that if it comes down to sex I can more than deliver. I'm here because, yeah, convincing tales of huge cocks still turn me on but I'm more here because , when you edit out the bullshit, these forums are a great place to talk openly about sex.
I don't see a lot of SPH in the forums, maybe I'd see more of it if I was a woman (or posing as one) on here.
