Needing advice for finding passion and attraction again for husband of almost 7 years

I've been married to my husband for almost 7 years now and we have one child together. Lately I'm finding I'm not sexually attracted to him and will make any excuse to avoid intimacy. My libido also hasn't been the same since having my son, I used to love sex and now I feel like it's a chore and very mundane. Even when I tell him what I want him to do he just doesn't quite do it the way I like. I feel like a complete ass as I'm typing this but I genuinely want to re-connect with him and not sure how to go about it. Any tips from anyone who has been in a similar situation and has overcome it? Should we see a sex therapist? Kamasutra? I'll try anything (except threesomes they're not my thing). Appreciate any tips 🙏🏼
