Girls I need help with my guy?

My boyfriend is a psych major in college and has recently told me that he has a fantasy of hypnotizing me. He's been studying it awhile. He says that the idea of seductivly putting me to sleep and then brining me out of a trance turns his on and that he finds it . I am ok with a little dominance..but..should I let him hypnotize me? I've been dating him about two years and hes very very good to me but I want to know some opinions on this. Is this type of turn on weird and shoudl I worry? Or is it harmless and kind of cute. I have to admit I am a little interested in it. Also..would you let your bf hypnotize you if he found it ? Help me out.
