I only did coffee dates for the first meeting, and NEVER give a guy your phone number until after you've had a coffee date - that's a good way to end up with dic pics.
You don't want a guy to have your phone number, last name or address until you've at least had one coffee date and feel comfortable he's not a stalker or crazy. Since my email address includes my whole name I never used it until I had met somebody in person.
Men complain in general that they don't get many responses on OLD, so if you see somebody you are interested in, you should contact them. Or at least "like" or "wink" at them, if the platform gives you the opportunity to do something like that. I had generally better luck with the men I contacted (because I already knew I found something attractive about their profile) than with the men who contacted me (who often hadn't even read my profile). Also, some men had their age limit set slightly lower than my age, but were plenty interested in me when I contacted them. So some likely prospects might not even be seeing you because of age, or geographical limits.
Andrew - it wasn't the duck in the picture that was disturbing - it was the fact that he was wearing a BATHROBE while holding the duck.
