Hi Mandy,
The best advice ever given to me I got from my trainer TALK, slowly. The scariest thing in the world is the fear that you meet someone you really care for and you tell them how you feel about something and they don't accept you for it. I very recently went through the same situation with my sweetheart I'm a trained dom and have been in the lifestyle for seven years when i met her she had never even heard of anything like it. I started very slowly, subtle hints, joking around a little, left a web page or two open, it slowly built her curiosity. I started talking to her about things that turned her on and started to lead the questions to tell her things I liked. I didn't jump right in a say "hey my turn on is to tie you up and use you till i have had my fill." pretty sure that would run just about anyone off, but i started with small things like i really like to be on top, and i really like to hold your wrists. I kept it really lighthearted she laughed at most of it but it planted the seed and thankfully human nature is curiosity soon she was trying to guess what i liked. After awhile when the time seemed right we had a little more serious talk and i told her my background, granted she wasn't sure what to do about it at first but i reassured her that it wouldn't change things and I reinforced that if she wasn't ok with it it wouldn't be a make or break.. I can't speak for your man but most guys aim to please and i have a feeling if you take it slow and "lead him to take the lead" you'll find things working out in no time.
