I need some advise, my partner and myself have been dating for over 3 years now but for the last 12 months my partner has had no sex drive.
We have a fantastic relationship and are like best friends but when it comes to intimacy, it really doesn't excist. We have discussed it so many times but she is adimite that she doesn't want sex ever as she has no desire for it. When we talk she admits she has masterbated only a few times in the last 12 months but she really doesn't enjoy it. We both feel bad about this situation as she wants to please me but can't, I want to respect her but really miss having an intermittent relationship. She does suffer mental health issues and I thought due to depression could cause lack of sex drive. Im not an egotistic man I would just like to bring the spice back into our relationship. Is it possible or is it slowly dying. Thanks my age is 30 xoxo

Sure, lack of sex drive usually goes with depression.
Couples have to compromise all the time. She needs to put a little effort into having sex for your sake, and you need to cuddle and sweet talk or whatever she needs to help her at least enjoy some of it. We don't know her side of the story, or if she is missing anything from you. (Sweet talk isn't 10 minutes before you have sex; it's all day long. Telling her she's beautiful in the morning, wrapping your arms around her at the sink at lunch, and nibbling on her ear while watching TV after dinner can have an effect on how she feels hours later.)

How old is she and is she getting treatment for her mental health issues? Is she on any medications including birth control/contraceptives?
