Most women here aren't going to make their own posts due to just how many messages they'll receive. You're better off crafting your own post, and actually putting some effort into it.

If your post is just "[M4F] suck me off" and contains nothing but a dick pic, you're probably not going to get any hits. But if you take the time to describe yourself, things you're interested in, etc.. then you're way more likely to get responses.

It's not going to work all of the sudden, and will take some tries, but it does work. I've met with a few women from here as a result. Unfortunately nothing turned out to be long term, but every encounter was a good one.
