3 year relationship little to no sex

Tara

I’m in a relationship with a friend that I grew up with. We have known each other since I was 9 and he was 12. We rarely have sex and only if I initiate it. Growing up he was kind of a sex fiend- he got around... We get along well within the relationship. Only significant issue is the little to no sex thing. Yes, I have discussed it with him on multiple occasions and no changes. Most of the time he sleeps on the couch so, my 8 year old has been sleeping in the bed with me. It’s like he gave up. Not sure how to fix this. Advice?
