In my experience, the majority of guys I've talked to online didn't have many. I'm not saying I'm perfect, I'm the most introverted person I know and I am shy but I do try to at least be a little social. It's more easier when I have something in common with them.
In the whole online thing, I met only one person who I felt a little connection with. He was much older than I was though but he looked attractive to me and we had a few things in common. The drawback was he was a somewhat closeted bi man. He started getting less communicative as time rolled on and that's what burned the little relationship out but compared to the other guys, he was probably the best in the beginning for me.
Like another user said, I'm not one for meaningless anonymous flings. I would need at least some little connection to feel comfortable doing it. I feel this is a big reason why guys lose interest in me real fast. Moreso the people who chat me up with little words like this...
Guy: How are you doing?
Me: I'm doing alright. How about you?
Guy: Good but I'm a little horny. Got any dick pics?
Me: Sorry, I don't do nude pictures.
Guy: *doesn't respond*
That's the majority of how some of the chats I get go. I don't post nude pictures and in my profile, I make it clear to not ask me but they still do.
I also have to agree with Integrity, I once chatted with a guy who I thought was hot on a site and all he would talk about was working out, being bored, and sex. And while that would be ideal for a lot of guys, it isn't for me. I like to workout but I don't like talking long periods about it. So the conversation wasn't very stimulating to me and I grew disinterested in the guy. So it proves looks open the door but it doesn't always mean you stay in. Or something like that. lol
I also agree with the whole ebonics thing. I don't text/write in ebonics and when I do get someone who message me or I message and the type like that, it really makes me cringe a bit. lol
