I can't really seem to look at your profile without making an account.

My wife wouldn't like that.
But there is a major problem with those dating sites. People are always trying to find their perfect match on those kind of sites. Like they want the whole package. Nice job, very attractive, great personality, and other ridiculously high standards. And one bad line can turn you a person off from your profile. Like I tried a dating site once before and said that gender roles were important to me, but I meant I like cooking, clean, and wouldn't mind being a stay at homer. After I realized the problem. I got more responses after I changed that.
The way that worked best for me, is I messaged like 40 girls in one day. Most will reject you, some will ignore you, and a few will reply. But only the people that reply really matter. I made sure to talk about myself a little and asking questions. Like, "I'm into all kinds of music, mostly rock and punk. What do you like to listen to?" No questions, usually meant no replies. But if you can get them talking enough, you got a chance.
It takes a lot of work, but you're attractive enough. My Dad met his girlfriend though a dating site. They are completely boring together, but a really good couple. All they do is sit outside and watch the corn fields. Like seriously. You just gotta ninja your way through all the baddies.
