Bf having less sex after miscarriage

So I have been dating my boyfriend for a little over 2 and a half years. We have lived together in our own apt the entire time. He's 20, I'm 19. Both graduated college, I'm
An EMT and he's a mechanic. Here's the thing, about 2 months ago I had an abortion which I didn't want initially but he wants to be able to better provide for our little one and he wants to travel and have fun just the two of us for a couple years. It was the hardest decision of my life, I didn't want to have the abortion but I felt I needed too, so I wouldn't disappoint him or his family. Ever since then we barely ever have sex. Every time I want to he says I need to get him in the mood, or make him want to. But I always please him when he wants. I can tell he is genuinely very sad about the abortion, but was able to move on. Any advice? How do I confront him about this
