Mr. Mojo Risin,
To help we really do need to know her limits and all that good stuff. Not to mention how arousing it is to read what turns other people onFirst I will suggest safe words. I use yellow for ease off or give me a second, red for stop whatever is happening at that moment and green, green, green when I want the play to escalate. Moaing harder harder also is used as a susitute for green. ~grins
Being the dominant entails a lot of responsiility but also remember you are both learning ang growing together so relax and enjoy each other. I don't really know your wife's mindset or needs so I am only going to give some basic suggestions.
If she gets home before you do and you don't have children running around. You can have her meet to at the door naked and kneeling when you get home for work. She should give you a well deserved welcome home kiss and I don't mean on your lips. This can also be subsituted as a requirement for you entering the bedroom at night. Just a warning don't get lost in the feeling or the nights play may be over before you know it. A blind fold will also add to the experience.
The more information you give us on her needs the more we can help with suggestions. These I think are pretty safe and hopefully do not infringe on any of her limits.
You both have a wonderful and exciting time a head. Remember to talk about how things make you feel. Understand that not every experience is going to blow your mind away with excitement or arousal but that even those experinces will bring you closer together. You will learn more about your needs as well as having the joy of sharing your partners experiences.
Just one more thing. BDSM can be very intense emotionally for the sub as well as the dom as you move into more extreme paly. So someone saying red and sobbing their eyes out does not mean that hurt them beyond repair. Sometimes just cuddling until the emotional or physical stress in over is all that is needed then of course talking about it later after you have made passionate love helps.
