First you naturally want a date with a woman who smokes well.The next step is to hope you get one who likes to smoke guys.
When it happens you will know it. No conversation or request is necessary; her eye contact and expresssion says it all.
From that point on you will get smoked untill you are dizzy; you could talk about it then or wait untill she makes a comment. Either way as long as you date her it will be a part of the relationship.
