Am I being used?

I was really close to this guy and we liked each other heaps, then he called me some pretty bad names, so I went off and called him some names. We hated each other for ages. We would be sorry and loved each other as mates again, then have another fight. The same things happened over and over again and I kept falling for it. Eventually I gave up.
4 months on after not talking, he sent me a text saying we needed to talk and he would call me in half an hour. Half an hour later he called me and said he was sorry for being such a loser to me and that after hours of thinking about it, he finally woke up to himself and he knew I was worth it. He says that he likes me and wished none of that stuff really happened. But as we keep talking he says he wants me to give him head and send photos of me to him. Every time I ask why he wants photos, he says ‘because I like you and I need you’.
Everytime I say if you like me and need me you don’t need photos and for me to do that stuff, he says ‘please babe’.
He has never said he likes me before and that he needs me and that he has woken up to himself and that I’m worth it, so I don’t know if this is just one of his little games or if he is serious.
He is a really nice guy when you are on his good side but otherwise a complete loser when your on his bad. He is being really nice except for the things he is asking for…
Am I being used?
Is this one of his little games?
Should I fall for it and see what happens?
Help me?
