My Boyfriend's doesn't feel like having sex anymore! What am

Hi. My boyfriend doesn`t feel like having sex like all the time. I don`t know what is wrong with him. I tried everything. I tried to look different, to act different. I tried to make him jealous. Nothing really works. He`s just not interested in sex anymore. So we broke up, a month ago. I have a new boyfriend now. He wants to have sex anytime, anywhere. I hate sex in public, but I can`t tell him that now. First I want to enjoy for a while. I had a long pause.
