I use different kinds of leather whips, crops and spankers (paddles and floggers) and of course also my hand!
The following things are important for me to know when I am going to spank somebody:
When I am spanking somebody, I follow his reactions to see that he is still OK about what is happening. Spanking must be felt but it must not feel too bad. It should still be enjoyable!
Spanking must also be safe so the only areas to hit are the bum and inner thighs where there are big muscles to protect your insides.
If you prefer a mild spanking I can do it so that it will not leave marks nor feel too painful. A mild spanking may work best for you if just thinking of being spanked turns you on — thus, a mild spanking is enough to fulfil your fantasy.
A medium hard spanking makes your bum go red but that kind of redness usually disappears fairly quickly. For some this type of spanking is hard enough to stretch their limits the right way so they do not need anything harder than that.
A hard spanking always leaves marks which usually take several days or longer (up to several weeks) to heal. However, it differs a lot between different people how bad marks can be and how quickly they heal. Those who are into harder spanking are also welcome to visit and they can be certain to get proper but at the same time safe and individual treatment.
