Not being face to face with you, the sexy girl whom you send message can reject you instantly or just overlook your message; 
in this case, you need to figure out how to attract her without being present before her.
For example: send a message to a hot girl in MySpace/Facebook state "I am positive I have met you the other night".
Of course she will deny that; if this happen, reply by saying "Nah, I am 100% certain it was you. You were that drunk girl that hitting on me and my friends the whole night".
You pine for individuals to believe you're cool for 
being so alluring to somebody that they established you 
the very night they met you. Yes, internet dating helps you meeting new individuals who could be your 
life partner. Those who reported being attracted to both sexes, however, had significantly 
higher scores, on average, than those only attracted to one sex.
