Welcome to the forums. Glad to see you are taking a plunge and becoming a Domme. I hope the learing curve is not too steep for you. There are a lot of people on here with lots of wonderful ideas. I would suggest posting something in the General BDSM forums (My BDSM life may be the best option here) to ask what you ask above about tasks for your sub. Tell us all about him and you, your likes and dislikes, and I am sure there will be ideas aplenty.
