I'm surprised by some of the other replies here. I like dirty talk. Some of the things that I like in this area would turn others off. We all like different things, so communication is important.
Turn Ons:
Asks what I like
Listens more, talks less
Is clean and well prepared (married guys can't carry condoms, etc)
Genuinely tries to deliver
Keeps a squeeze bottle of honey on the night stand...
A nice collection of toys to choose from
Turn Offs:
Dishonesty
Upselling
Poor hygiene
Talks about other men or family/money problems.
Psychotic episodes
