I think everyone has limits whether you call them that or not: things you will or won't do. As for a list: I too am old enough to have come of sexual age in the era of AIDS, so I've been having sex off and on for many years and my 'limits' today are very different than they were 10, 20 or 30 years ago. For me, They just keep broadening & changing. I believe sexuality is fluid and desire, turn ons/offs, limits etc will also, hopefully change with time. A couple of longstanding hard limits are no scat and no choking/asphyxiation. Most other things are a matter of degree/subjective rather than the what of it. I like some bdsm-y kind of stuff but not all-eg. a well timed spank or three might be great but not into marks or welts... I like some bondage but don't ever gag me. What do others think?
