For kicks, just some of my two-cents and experience.
GUYS:
-If you make stupid, perverted, or half-assed comments as messages, you're doing it wrong, and get what you deserve, as well as making the rest of us look bad...
-Women have heard it all before, and their inboxes are filled with it. Try to spark a conversation about something less obvious. She might take a while to get to you, but it'll be worth the wait.
-NICE GUYS! - Of course women want a guy to treat them right. Who doesn't? But there's a difference between being genuinely kind, and being a pushover, or 'too' nice because you're so excited that a girl's into you. Be you, know yourself, and be confident in who and what you are. Not all women will want you, but the right one(s) will. The rest, you won't worry about, because when you're confident in yourself, it's a whole different world =)
LADIES:
-If you have something like "say something other than hi" on your profile. Either make a point to respond, even if just to say no thank you. or never again complain about what guys do. It's kind of a joke to expect guys to make all this chivalrous effort, to impress you, and MAYBE you'll reply? That's cute.
-If you "know what you want, sorry", then you're an idiot.
-OKC is like a store. If you only ever shop at one place, you're only gonna find the same shit. every time. i.e., either expand your options, or shush lol
-If you feel like the guys aren't biting, same advice. Be you. Tall, short, fat, thin, whatever. You are you, you're fine the way you are, and any guy who can't realize that is a sorry loser, and you don't want him anyway.
Everyone, in the dating world needs to lighten up a bit, have fun, stop being TOO picky, because yes there is such a thing, and maybe meet the love of your life! ;)
