Leave a guy speechless

Love his favorite book/movie, flirt with all the time and spontaneously, and be direct.

First, In what way, do you mean sexually, mentally, emotionally... Is this a boyfriend or somebody you like and you are trying to attract... You need to let me know more before I can give you the appropriate answer.

Do things out of the ordinary that you wouldn't normally do.Surprise him,90% of the time guys will like anything a girl does in that kind of situation.You could dress up in some lingerie to really blow his mind,or try new things that he would like.

Well if you're sexual give him really good sex I mean study playboy and see what he likes.
