A drugs forum is not a suitable reference. A suitable reference is a peer reviewed scientific paper published in a journal or other such source. These present facts with research carried out in controlled environment, with reproducible results, or stating their sample size with controlled measures in place as well as having control samples as well.
May be that some posts on the forum are referring to research papers produced by Doctors. It may well be that many of the posters
are Doctors, but a post on a forum is not a reliable information source.
And just for entertainment - you are telling everyone it's a "well known fact..." regarding what you think, whilst dismissing their "well known fact..." as being
wrong. The irony of arguing against someones well known fact being wrong whilst your well known fact is right, coupled with the attention to semantics in the original offending post, should be highly amusing.
But I kinda doubt you realised
As for the original post - the only time I felt guilty was after my first private with a lady I had spent lots of time chatting. At the end I had said "It was fun", to which she replied "for you, yes".
That was feeling guilty, and whilst we still chatted for many more months before she quit - I never took her private, or in group, again (no, I didn't exit asap either
). Nearly 30 months later and I still remember it - it made an impact.
