It's exactly what it says on the tin really - the reason I bring it up is because for some reason 4 or 5 lads I know have decided (independently) to give it a go in the last few weeks. Different reasons were given - one was training for a marathon and wanted the boost of extra testosterone for example, others were just curious to see if they could do it.
Is this a new thing that guys are trying? Seems like hell to me - extra hormones, extra aggro and no porn.
Anyone ever tried it? How long did you last? Question open to both sexes by the way - I'm sure it's a bit of a biological/psychological hurdle for wimminz to go cold turkey for an extended period of time too
