Depression Killing My Sex Drive, Hurting My Relationship

Yeah... for a while in other relationships i would either shut down when sexual stuff was involved or would do it anyway (both options sucked). In my most recent relationship though, i feel open enough with my partner to just tell them look dude, i love you a ton but sometimes when im depressed i just dont want to have sex. Its not a you thing at all, and i still care about you. Ill let you know when im down to have sex. Being completely open while still understanding and acknowledging how the other person feels is the best thing i can suggest.
