Found this girl on Zoosk.....her profile says:
"I'm 18 years old. I like to party and have a good time. I love da ganj. I like guys and girls. I've got a pretty crazy life. Oh and I love sex

"
So I sent her a message saying, "Since our profiles practically mirror eachother, I have to ask what is the most adventurous thing you have done to, or for a guy?"
Still awaiting a reply.
As for the other openers....on datehookup.com.....I've sent out about 20 messages (not many decent looking girls to choose in my surrounding area on that website)....out of those 20, about 4 or 5 have not yet read the message. The rest have read the message. 5 blocked me. No one has responded. My profile states what I'm looking for, and my message consisted of something along the lines of "Hey, I came across your profile while browsing the website and thought you were kinda cute. I would like to see what else you're working with. Take a look at my profile, and if you're interested, let's have a chat. Talk to ya later, cutie"
I thought it'd be a decent message, but it hasn't triggered any responses...so clearly I failed haha
