Erectile Disfunction and feeling Desire

My fiance has a ED problem which he takes something to help with it. We were TTC so he needed to stop. We got pregnant that led to a miscarriage. I have to wait another week to have sex again. It's been 3 months without sex and I miss it so much, can't wait. My fiance though said he doesn't miss sex. I asked if his desire for me is affected and he said no, afterall he grabs me all the time which shows he wants me.

I'm not really sure if he's just saying that. My question is can you have no desire for sex but want your partner sexually still? To me it sort of contradiction.
