The first time you have sex if it's been awhile and there is any emotional weirdness on either side .... it's an unexpected bonus if it isn't a little hinky/mixed feeling. What you got is, IMHO, par for the course. This sounds horribly unromantic, but it's like that first plane ride after the one with all the scary turbulence. Good, that's over, now let's move on.
Actually, I think it's a net positive if neither party has either (a) freaked out and pulled back completely, OR (b) started going on and on and on about how awesome, best ever, etc. Sounds like you are both in an authentic place.
