How much effort do you devote to finding a partner on dating sites? Are you looking through profiles carefully, trying to determine if you would be a good match with those people or are you just sending copy pasted messages to anyone who catches your eye?
I never respond to messages that look like they've been copied and pasted. I receive far too many messages to respond to every simple greeting. I will only respond to someone if they use a creative opener or mention something in my profile (such as a common interest).
Having a fully fleshed out profile with pictures will also help your response rate. Avoid mentioning your fetishes unless that's the only thing you're using that profile for (and I would suggest you use FetLife only, in that case).

Give up online dating. It's not worth the headache. It's just another thing geared towards women.
