Most Helpful Guy
The truth is guys aren't mind readers, we always want to know. As for being pushy that lies in the delivery not the act. For instance if its something sexual, start making out with him, then bite your lower lip tell him, "Ive always had this fantasy" then whisper in his hear what it is. As for "mystery" its not sexy its confusing as hell. If you dont know or want something new, ir want to feel mysterious, just say "surprise me." But if you do that dont be upset if the surprise isn't exactly what you wanted, a lot of women are like that.
The only real exception is timing. For instance if you just start dating and start talking about marriage and kids, that will freak a lot of guys out. Guys still want to know, but braod strokes in the beggining, its more about getting to know each other.1
