thoughts on sex during early recovery?

I'd always struggled during sex and I think I discovered it's because I struggle with PIED. I'm only a couple days into absolutely no masturbation AND looking at porn. Which is something I haven't done in a very long time. But I've been keeping this away from my girlfriend and obviously at some point or another she's going to want to have sex.

So my question is, should I try? Should I push off around a week or two? Should I try to avoid sex at all costs? Or any other thoughts would be great!
