Before I get started, credentials, so to speak. I've been in the lifestyle various ways for about five years now, more as a submissive than a Dominant until more recently. I've studied more books than I can list here, attended a number of seminars, and even spoken on a couple panels in regards to this subject matter. This is the voice of experience.
First off, you seem to have some online experience, either in chat, a website, or somewhere like Second Life's online community. I say this, because you are using proper slave caps. However, this also gives away that you do not have much experience in REAL LIFE.
-That is not a slight against you.
If you're new to this, in real life, you need to start slow and easy. I personally tried to jump headlong into this, and while I was entirely ready, I've found that Dommes and Doms generally are not. In fact, a healthy Dom\me will actually distance themselves from someone who is. In short, it tends to get rather ugly.
Additionally 'sex slaves' do not generally exist unless you're either an ACTUAL porn star, an undocumented immigrant, or have absolutely struck gold. No Dom, Domme, Master or Mistress wants a 'sex' slave. Most of them don't even want a slave, that brings extra responsibilities. But if you choose this lifestyle, understand that not everything they expect of you will seem sexy. Service usually involves household chores, and sometimes painstaking ritual to be just the way they want it. Many Dominant folks are at least somewhat OCD, and they'll expect you to have things just right.
Start off by finding the local 'scene'. This is the group of people near you, who meet publicly. They often discuss REAL LIFE relationships in the various forms of BDSM lifestyles. It is VERY important that you understand that online chat is never going to substitute for that, ever. Most the people online who claim to know anything are absolutely full of it. No 'hardcore' Dom who actually knows what they're doing, is wasting their time goofing around with the S&M equivalent of cyber sex or slavery.
A quick pipl search leads me to believe you may be somewhere not *too* far from chattanooga. This appears to be your nearest Craigslist community, if this is the case, post an ad there. Post it in the 'Platonic' section, NOT any of the m4w, or casual encounters sections. Post the ad to say you're looking to meet like-minded people, or get involved in any meetings or groups that may exist near you. Most major cities have a large scene now, it's just a matter of finding yours. Here's a link to this city's craigslist, in case you're not familiar.

While slavery may very much be for you, it must be transitioned, and the only way it will last, is if that transition, and yes the collaring too, take at least a year, preferrably two. Any sooner than that, and it tends to be an unstable relationship that leads to a lot of pain.
Believe me, when you're in a relationship with absolute power exchange, the pain of a breakup is infinitely stronger. It's like they're not just rejecting your personality, they're not just upset... It's like everything that you are, everything that you've offered them, 100% of your essence and your eagerness to serve can never be good enough... It's one of the hardest things you can deal with. Stability is paramount.
Check out the scene, go to seminars, talk with folks who are really in front of you, who've really had a slave, or really are a lifestyle submissive. Ask them for advice getting into it, finding a partner(s). Don't let the internet be your only source of information on this one, you can't afford to, or you'll never find a satisfying relationship of this kind. Once you've met folks who really do live this lifestyle, and who really do just exude experience out of every fiber of their being, who understand mental subspaces, who understand the phenominal balance required between masochism, service, and the chemicals produced in each sensation... It's never going to feel right.
ADDITIONALLY STOP POSTING THE SAME QUESTION FOUR TIMES IN A DAY. THAT'S A SIGN OF A S.A.M., AND DOMINANTS *HATE* THAT.
