Sexual attraction

Okay, so me and my boyfriend have been together what will be 4 years in July. We used to be so close mentally, emotionally, sexually and physically but recently we’ve been through a lot and had a 2 month break but are now back together. It’s what we both want except... for a while now, I’ve not been sexually attracted to him. We recently had a conversation about our sex life and ways we could improve it so it doesn’t feel like a chore but I just can’t bring myself to tell him he doesn’t really turn me on anymore. I don’t know what to do. We’re more often than not open and honest with each other I just feel reluctant to tell him this in case it offends or hurts him. He already struggles with body image issues etc and I don’t want him to think it’s to do with that because it’s not; I love his body. It’s just his touch when we get intimate that I seem to have issues with.

I’m looking into seeing a sex therapist/couples counsellor I just don’t know how to bring that up to him either.

Any advice would be great. If I missed anything out you think would help in advising I’ll try and answer as best I can.
