...Simple answer: Be your self.
Ok, a little more guidance might help. First the DON'Ts.
Don't:
1. Try to use creepy pick up lines
2. Make up big lies about your life, your schedule, your intentions
3. Offer money for sex. Don't leave hints, don't use code, don't use TLA's (Three Letter Acronyms) like P4P, BCD, GFE, BBJ, etc.
4. Pretend to be a UTR celebrity, or a studio insider, etc.
5. Push your good looks as a reason to hook up. It's about the cash, not your alleged 6-pack.
Now the Do's.
Do:
1. Be sincere, real, and honest (or as honest as you can)
2. Include some ideas of your likes and interests, your passions, and your life-experiences (past and hopefully future)
3. Show some personality.
4. Type enough to show you spent real time thinking about your profile.
5. Have perfect spelling and grammar.
6. Give some indication of your arrangement preferences: Discrete and low key, fun and adventuresome, casual and light, romantic and long term, etc. Do this without ever mentioning sex. Be careful about using "intimacy."
Pics:
1. More is better - 3 to 8 seems pretty good. I use 12.
2. If you must hide your face, have at least one face pic in your private area.
3. If you must hide your location, use pics taken away from popular landmarks
4. Use a mix of face and full body, casual/candid and formal, indoors and out, and alone. Pics of you partying with 4 strippers is a bad idea.
5. Use only real pics - no photoshopped pics of you driving a Ferrari or piloting an F16.
6. Use pics that look good on a screen. Too small and they get pixelated/blurry. Big, wide landscape shots with you in the bottom 5% of the frame are useless. Crop those.
Bottom line: Be a real guy, not a pickup douche bag. If she wants to bang beefcake, she will go to a bar and fuck that busboy with the great shoulders who lives on his buddy's couch. Instead, be they guy she can admire, trust and play with without drama or needing to meet you in your mother's basement.
Life is good
