I need to vent somewhere

So my boyfriend has an issue staying hard. Countless times we stop in the middle of sex and get nowhere with it because of it. He won’t go to a doctor for it. Yet he wonders why we’re not pregnant yet.

Plus when it happens he gets pissy and acts like it’s my fault. It makes me feel like shit. But when I bring it up he says he’s not mad at me he’s mad at himself when it happens. But he still does it every single time
