I also think it is ok to pm somebody who you think might be a good match, even if they do not say that they are looking. However, I do have some tips:

1. Check out their profile. Specifically check to see if they have a sub/dom currently, because this may cause problems.
2. When approaching them, make sure to use proper grammar and spelling. Write a complete response. Make sure to introduce yourself and explain why you are messaging them. Make sure to set it apart from a common spam message.
3. Do not be demanding or ask them for a favor right away, or ask if they want to be your sub or Dom. Start by asking them if they would like to get to know each other, or have a conversation.
4. Do not have any expectations. If you are turned down, do not get defensive, but instead thank them for their time and move on.

I have found that most people are willing to meet new people and are open to having a conversation. I see people getting defensive or putting up walls when they are approached by somebody who is demanding, rude or asking for things (ie. I need permission to cum from x amount of people) within their first message.

Being polite may not be a fool proof way to get a response, but it definetly puts you at more of an advantage.
