You may be pursuing the wrong goal. Taking strong T blockers to nuke your testosterone will likely slash your libido. However, if this was just about sex, if you were just horny…well escorts are are a thing. But people seek out partners for far more than just intimacy. The sex really is a small part of a relationship. What you’re really seeking in your heart of hearts is companionship, love, and romantic fulfillment. Nuking your libido won’t solve that fundamental human longing.
Also, you really don’t want to be without any active sex hormone. Your system can run on T or E, but it needs one or the other. With all your hormones at low levels, you’re at risk for menopausal symptoms like osteoporosis, cardiovascular effects, hot flashes, brain fog, etc. You could take estrogen along with the blockers to avoid these effects, but that would have severe issues (assuming a gender transition isn’t something you desire.) If you tried to take estrogen along with the T blockers, that would cause a high level of feminization - you would basically be doing trans hormone therapy at that point. And the E might cause your libido to come back as well.
Dropping your T level to near zero will produce serious long-term health effects that you really don’t want to experience. If someone told me they were, like, a non-offending pedophile who desperately wanted to nuke their libido before they hurt someone, well in that case I might say the negative health effects are worth it. But by doing this, you’re signing yourself up for serious long-term health effects, all for something that is unlikely to really solve the true source of your pain.
