Am I too readable?

First hand - what is the most likely position to hold a 5 in their hand for the straight? BB = you.
2nd hand - Shant has the plan to get more $. You told your villian with your bet that you were not afraid of 3 aces. This looks like betting patterns and position decisions, not necessarily reads of your habits. Also, I know some people call down new players early at a table to see what the new player is made of. Other players are tighter and fold easily to raises from new players UNTIL they get a read that is specific to you. Sounds like you encountered the latter tight reaction to a relatively new player at their table.
