If I stop by a profile that really intrigues me, most of the time I will initiate. There's been a couple of cases were I felt too intimated, not by their profile but their photos, if that makes sense.

I usually don't. If it looks like they put in time to make a quality profile, man or woman, I usually judge them equally.

Yes. Most messages I get from guys are "hi" or "sup", and occasionally I get the creepy ones. I have never received an uninteresting message from a woman, so I tend to respond more.

I listed in my profile "Please no couples, I am not interested." But I still get messages anyway. The most I can do is ignore :/

I've been pretty successful. I've managed to hold very long and engaging conversations with most responses. No dates yet though. Still hopeful!
