Why use a professional dominant.
1. They fit in well for people who are hiding their BDSM lifestyle from everyone including your family.
2. A good one will have every piece of gear you have ever seen.
3. A professional will be good at reading the sub and will keep you right on the edge of your personal limits.
4. Their experience means you are less likely to be damaged. By damaged I mean injury that is unintended.
5. Can provide a many kinds of BDSM experiences including, domination, bondage, medical, TV, humiliation and a variety of role-playing.
6. A good one will have a great fetish wardrobe to enhance the session.
Many of these have been done to me. I have been taken out to a public restaurant while wearing a chastity belt and one hand cuffed to my waist. It looked like I had a lame arm not bondage. I have been directed to run errands in the neighborhood while a remote socking device was attached to my balls. I have been whipped, pierced and branded while bound. I have been bound with leather, steel and rubber. I have been suspended, inverted, mummified, waxed, plugged and electrified. I have had my nose ring locked to the clit hood ring of a mistress while she kneeled on my gag straps to prevent me form moving or touching her sex.
These were all quite a rush and thanks to the diary that the mistress demanded I make by writing after session letters they are still a rush in my memory.
Other then letting some marks heal I have had no after effects.
