So I thought more about your situation and basically you have been making irrational decisions for a year. Sex does not revolve around orgasm. I understand that you are depressed and have no desire and cannot orgasm, but sex means a myriad other things above and beyond orgasm. It has multiple benefits, from the trivial - you are burning some calories which never hurts - to the non-trivial - you are connecting with another human being who is important to you.

Plus, when you have sex, you allow yourself to experience feeling wanted, and that is a natural AD that is cost-free and without side effects. If I offered you a free, effective AD without side effects and you said "no"... irrational, right?

Plus, you are a mammal... however much you busy yourself with intellectualizing and cerebral questions such as "is sex a basic need?", you are still a mammal, and mammals thrive on touch. That is what distinguishes mammals from snakes. So OK, you do not have the desire, but you can still cuddle and benefit from the sense of touch and that would work as an AD as well.

Sex means no sensory deprivation. Sensory deprivation is bad. So, another benefit.

Your r/s seems to be an exclusive one, so I assume that sex would be unprotected, which means that you can swallow sperm. I think that the act of swallowing sperm gives a woman a supreme sense of accomplishment, surpassed only by the act of giving birth to a baby (that one is the winner overall for sure). Since you are depressed, you probably do not have a lot of accomplishments, right? So why forego the few that you can have? The sense of accomplishment is another AD. So it is as if someone were giving you gold and you were pushing it away with "sex is not on the menu"!

I am sure if I thought more about it, I would come up with another half a dozen benefits of non-orgasmic sex, but I do not have time for that. Do this exercise by yourself - recall the good times you had with your bf and list every good thing besides the orgasm. You will be surprised with the long list you will come up with if you do this exercise carefully enough.
