Should i get an implant if I have zero libido?

[Topo22]

Long story short, in 2016 i got super sick, like I was poisoned basically, i think it was black mold but never totally sure. Later thought it was lyme disease. I was about 3 years into this hell of suffering extreme insomnia, night sweats, headaches for months, crazy anxiety, depression, joint pain, and much more that everything changed for me. I had moved, was getting better very slowly. Still has intact strong sex drive the whole time. I had improve tremendously. I discovered that antibiotics helped me (thus lyme hypothesis). I had 4 or 5 courses of antibiotics In a year in 2019. It was during my last course (Augmentin) that one day my libido turned 100% off. Like a light switch, i remember exactly where i was standing when it happened.

That was 6 years ago, since that time zero libido
i relied on viagra mainly, which worked super well, i had tons of sex even though i had zero libido. I have orgasmed every day just about since as it still feels good and i think its good for me. But in the last year viagra mostly quit working as well as cialis. I can still perform if i take 50mg cialis and 100mg viagra together but not always.

The thing is, i don't think anything is physically wrong with my penis unless viagra damaged it maybe, i can still get erect to mastubate but it takes a lot of stimulation and isnt usually all the way hard. In other words i would never attempt sex like this even if i technically could barely. One interesting note is that 3 years ago i contracted herpes 2 and during my initial outbreak my libido came back 100% just for a week, then back to zero.

I thought my drive and function would eventually come back and honestly viagra was working so well i just wasnt that worried about it. But now that I'm almost dead in the water sexual I'm asking questions. For the record i never took steroids or psych drugs or finsteride etc. I've tested my hormones 4 times in the last 12 months. My testosterone ranges from 800 to 1400 (naturally) my sex binding globulin is always high (50-70) free T is always in normal range, prolactin normal, and my estrogen is lowish 15-26. I'm not depressed, i workout, I'm mid 40s, dont smoke, dont drink, I'm not fat or super low body fat (21%).
Basically I'm here because I'm doing a few tests that i expect to fail and then ill be faced with some hard descisions. I plan to take HCG to boost my estrogen up a bit and see if maybe my super high SHBG is binding it up too much and in general to see if i experience any libido changes. If that fails, i will try Adderall to to see if boosting dopamine has any effect. I'm currently testing bupropion with no postitive effects. If all that fails i may test a dopamine agonist like cabergoline or pramipexal. But im not expecting any of these to spark my libido again which is why I'm here.
If i cant be horny and as a result cant perform then maybe i should just get an implant and at least solve one of those problems. At least that way i can entertain the idea of having a partner (currently single) but i guess the gamble is that i can orgasm now solo and it feels as good as ever but I'm afraid of losing what little i have left trying to gain more.
I know the people in this group have a world of knowledge and I'm all ears for any thoughts, advice any of you may have to help me plan out my strategy.
