I actualy never use winks and emoticons with girls. I think they look a bit needy. But some sentences on facebook and in text messages might look boring or emotionless while if I would say it in real life, a seductive smile and look might make the phrase more sexy.
For example, I want to send to a girl (not literally translated): "how loose did you get at [big party event]?", but I'm not sure wheter I should add a smiley, or keep it cool.
1) "how loose did you get at [big party event]?"
2) "how loose did you get at [big party event]

?"
What's the best of them? Just keep it cool with (1) (but maybe too cool?), or shall I go for the more open (2) (but maybe too open)? Do you prefer emoticons or do you rather not use them?
