I've been chatting to a guy online but am wary
I'd be more than wary, I'd be worried TBH.
Dom and Sub relationships, imo, work best in one of two ways.
- As part of a long term, loving relationship.
- As a finincial arrangement between the dom and sub
Ignoring option 2, i'll guess you're looking at option 1.
Think of a Sub / Dom relationship as being the same as any other relationship. you need to build good solid foundations of trust and love etc before you even think about handing someone the permission to be your Dom. I would never, ever, ever suggest anyone be a sub for someone they barely know or they don't trust 110% percent.
If you're talking about being dominated by someone you've not met, someone you don't know etc, i'd be very careful. You might not feel comfortable enough to explore as far as you want to go, he might take it too far and it slip from sub / dom to abuse.
Keep reading stuff, maybe join a sex life forum, Love Honey have a very good one, they'll be bale to give you all the detail you want.
