I don't know why it's happening to you. I won't refer to you as creepy because I can't judge, it's the first time I see your username. You can't please everyone. Even though you feel like a lot of people block you, I pretty sure there are plenty of others who haven't blocked you. Don't worry too much about that.
Probably because a lot of your questions are sexual and your profile mentions sex a couple of times as well. A lot of girls on here have had encounters with perverts and probably just want to avoid them, so you mentioning sex so often, makes them think that you are one.
