You sound so incredibly immature. Just because you don't cheat, or do anything illegal - as you keep saying, it doesn't mean you're not hurting anyone! What about all the girls feelings when you break up with them for the sake of it? You seem to need a girlfriend for validation in life. It's like the people at secondary school who just had to have a girlfriend and would ask everyone out until they could get one. You sound like a sad person. I think this is a troll, but if not, your sister must have hit a nerve for you to make a thread, because she's absolutely right.
