I'm the reason for the dead bedroom and I don't know what to do

I'm the reason for the dead bedroom, and I don't know what to do.

So, the long and short of it, is that I, 29LLM, and my BF, 32HLM, don't have the same libido at all due to me taking and then getting off of Lexapro almost 5 years ago. It gave me PSSD, numb genitals, and killed my sex drive completely.

I had talked to my doctor about the issue, ive talked to my therapist about the issue. Nobody knows how to fix my body chemistry so that I can feel lust again.

I was on Wellbutrin for about 6 months most recently, and while it did gently increase my drive, it also apparently caused me to no longer have any "buildup" when I have sex, and I would just explode instantly without warning. Seriously, the weirdest thing!

I was happy to feel a little bit of something, but the fact that I had no say in when I came was an absolute bummer. It was often times over before it started, and my libido would of course hit the ground after I came.

So, I came off the Wellbutrin because of that and because it made me feel very tense. Unfortunately, I stopped it and my bodies libido hit the floor again. Now I'm back to no libido, or interest. I just don't know what to do anymore. My boyfriend is understanding, but we both agree that it's not fair that I can't help him with his physical needs. I just don't feel like it :( it's not interesting at all to me anymore. It feels like a chore to have sex or masturbate (which doesn't happen often).

I'm just... I'm lost. I don't know what to do. I miss my sex drive. Does anybody have any experience with PSSD?
