PE was somewhat under control but it’s bad again. I got extremely sick and the PE came back and has remained. Sometimes if I get past the initial urges to ejaculate I can last much longer but this isn’t great for traditional sex. Any suggestions?

Had PE under control for a while after some improvement but then I got extremely sick and have had much worse PE ever since. I have noticed if I can get past the first urges to ejaculate I can last much longer, however this isn’t entirely possible with traditional sex. Any ideas about what might be causing the returning issues?
