My numero uno hard limit is:

"Absolutely no "Spooning" (cuddeling after sex) lol,

"When you get done making use of me please untie me so I can pace and enjoy a few smokes while I come back from subspace on my own, If I need your assistance I know where to find you."

Well when I first started I got lucky, my very first dominant and his wife questioned me at length about it all before they decided to include me in thier household.

I was pretty up front with any other doms/dommes I have had since then. Even if some of them were not so up front with me. I should have in hindsight been much more proactive in establishing hard limits with them prior to any contact up front or insiting that any gray areas be hammered out before hand.

No snuff, skat, pee, kids or permament physical harm were for the longest time my only limits.

That has changed a lot over the years.

I have in some ways if any thing many more limits now than when I first started.

Some of them developed due to bad experiences and others due to refinment of my desires over time.
