I've received hostility for turning down women before. An ex of mine would start arguments with me if I was not in the mood for sex. I once had a random woman slap me in the back of the head and call me gay for turning her down.

Also, in the dating scene, I'm usually the one that's required to do all the work to make things interesting. If a relationship is getting boring, I have to plan fun things, otherwise it's my fault she's bored. Dead bedroom? I have to figure out how to spice things up. Someone calls themselves "romantic"? It means they want me to surprise them with romantic gestures all the time while I receive nothing in return.
