I have tried it in the past. Would add random girl to friends (couple mutual friends), if accepted waited day or two and after would write them. To be honest, success(sex) ratio is 2 girls from around 20. I'd like to ask, what would be good tips for this method? What can be a good opener? I usually start with " Hey, how are you? ". But as you see it doesnt work all the times. Sometimes they just "seen" it. Any advice?
