I don't deliberately keep my sex life private, and I don't delibarately make it public either. I talk about my sex life when I feel comfortable enough to do so, I'll brag occassionally if I got up to something particularly hot, but only with people I know would be interested. I certainly don't make my sex life my raison d'etre though, I'm not one of those tedious "sexual crusader" types who have little or nothing much else to talk about, and think that being sexually "transgressive" is really fascinating, even though their sex lives sound pretty boring in fact.
