sex after baby 🙈

so... I had my little girl 14 weeks ago and I have only had sex 3 times. my husband keeps trying it on, but I either have no energy or I'm simply not in the mood and I can see it is getting him down as I know he thinks it is him and not me. I have tried explaining its me and nothing to do with him but i knoe it dtill gets to him, i mean who would it not effect? When I gave birth I did tear and I think I am slightly nervous not only for it to hurt, but also in case it's not the same for him or me. Basically what I'm asking is did anyone else have this issue and how did you get over it? thank you :)
