I live with my ex and I cant wait untill I get away from hin

Even thought we broke up, he still wants me to give him head and find his next girlfriend. I cannot afford to live by myself but currently working towards better finance for me. I am not attracted to this 37yr old man and im 24 btw. We dated for 4 years the sex was terrible and he got 1 baby out of me, still asks me for money even though he makes more than me. Could someone give me an oral recipe I could put in my mouth so I could irritate his penis. He cant take no for an answer so ill force him to stop asking.
