I wonder why you are techically a switch. Do you really want to dominate or are you a sub that likes to just NOT be a sub sometimes? If he wants to be dominated is he really someone you want to be with? D/s relationships are way beyond the normal realm. It takes talking about expectations. What each is really comfortable with to develop a deep trust. I'd suggest writing down separately what you each want from the relationship then sit down and read your goals. Compare and contrast them and find if or where they mesh and start from there. If either of you is uncertain about how do Dom/me then perhaps just some kinky sex is best.. IMHO
