Yeah, if there's something that doesn't feel right to you so early on, he's probably not right, at least not for you. From what you say, you seem to know pretty well what you like and what turns you off...just go with that.

And just in case you're wondering whether all doms are like that...they're not. I personally don't like the show offs either - casual confidence turns me on. If someone tries to impress too hard, I start getting the idea that there's more hot air than substance involved, lol. Someone who feels comfortable with who he is and where he stands doesn't have to brag about it.
