I would definitely advise a inexperienced sub to avoid an inexperienced Dom. It's not really my place to give advice for an experienced sub, and I doubt she'll need it. I'll just leave it at that. I think that the major problem is that inexperienced Doms generally lie about it, and inexperienced subs haven't learned how to smell them out yet.
My advice to inexperienced Doms is be very honest about any insecurities. If it turns her off, fine. That's better than anybody getting hurt.
Tom of Sweden...I agree with you, great points.
