No sex life in a relationship

Harleigh

Me and my boyfriend have been together for 8 months and our sex has always just been alright. For the last 12 days he hasn’t touched me at all; I try to make advances towards him but he always says he’s to tired or just doesn’t feel good. I’m not worried about him losing feelings for me, he’s very sweet and loves to kiss and cuddle, but MIA when it’s time to make love. What should I do?
