I will start by quoting the late great dominatrix, Gertrude Stein

"Hard limit is a hard limit is a hard limit is a hard limit."

Now sometimes "pushing limits" means testing pain limitations. OK I am a pretty heavy maso I have have some of that. I will not that a positive outcome is not assured

OK and then there is expanding interests. I think there is some confused subs who think everything not checked off as an interest is therefore a "hard limit". No it's not. I have expanded my interests by letting some trusted ladies do things not listed as an interest so as they are not a hard limit.
