Warning - mature people only!
Actually, these sites are more technical and focussed on discussion, so they're not that bad and don't contain much in the way of adult material. Don't ask why I found these, long story and very boring.
Anyhow, I couldn't believe I stumbled onto these sister/brother sites. Great names and actually quite funny, healthy to read and informative (in a sense)!
