Low libido

Any tips and tricks for increasing my sex drive? It’s starting to hurt our relationship. I never want to have sex; as soon as he makes a move my defenses go flying up and I generally get super grouchy. Even though he’s my partner and I love and trust him, being touched sexually by him (or myself, even) has started feeling really icky, like being touched by someone who shouldn’t be touching you down there. I hate feeling like this, and I really want to be a sexually fulfilling partner, you know? Right now I’m trying a maca root-based tincture, plus clary sage and nutmeg essential oils. We’re both 23 and we’ve been together for a year now. Thanks :)
