My boyfriend and I practice safe sex, but on one occasion we did not use a condom and he got a fungus on the tip of his penis (like weeks later). But a few days after(we had unprotected sex) I had a yeast infection, it had felt funny down there prior to when we had sex but i just ignored it, anyway he wants me to perform oral sex on him, should i? He was treated, got the anti-fungal cream and an oral tablet. Since then he's fine, this is a few months now.
