insertionist...?

maybe tmi but okay so this guy I've been seeing (and having amazing sex with) brought up to me the other day about how he's kinda kinky. When i asked him about it further, he mentioned toys and said he was a big insertionist and is interested in using toys on me. not really sure how comfortable i am with this yet but figured I'd ask, anyone have any experience in this? I'm curious to see if this would be awkward or why not try?
