Boyfriend won't have sex??

My boyfriend of 4 months and me have had sex once in the past 5 weeks. He had been hospitalised a couple of times due to inflammation round his heart and was diagnosed with a condition called pericarditis, which can last for up to 6 months, and causes his heart to race and is very painful for him.The problem is that he says he has no interest in sex the now or for a long time as he still feels I'll. I love him and know that sex is not everything, but he has been doing his weights okay, and I know he has been looking at porn, which doesn't bother me, only in the way that because he seems able to watch it and exercise it feels like he is just making excuses not to have sex with me. At night we cuddle up in bed every night, and he still tells me he loves me so he's not completely pulling away. I just feel really unwanted and unattractive now because of this and am not sure what to do, does anyone have any advice?

So...he can't manage sex with you BUT CAN WITH HIS HAND and can't manage physical strain with you BUT CAN WITH HIS DUMBBELLS. Yes, clearly he's making excuses. So I think you need to tell HIM this and see what he has to say for himself.

Well, it's quite possible that you're just so damn sexy that you're too much for him. Your options: 1. Accept that you're not going to have sex often. 2. Talk to your man and work something out. Alternatives? Idk. Just let him know that it's hard for you. 3. Decide it's just not enough for you and break up with him... Or maybe if you tell him it's too much for you, if he cares about you enough, he'll be better?
