Is there any castration medicines I can take?
This wont answer the question, but I hope you read it anyway. The problem isnt your sex drive, in the same way that food is not the problem for people with eating disorders, and sad movies and songs are not the problem for people with depression. We can develop an unhealthy relationship with all aspects of our life, and that includes sex. This is especially true for people that have been recently diagnosed with something that relates to their sexual health. Sex and sexuality are highly stigmatized topics, and the power of the negative messages our culture exposes us on a daily basis can cause irreparable damage to our sense of self-worth. It happens more often than you think. Its so common, in fact, that clinical protocols in my country include referrals to therapists after the diagnosis of a long list of conditions that affect the reproductive system. Please know that you dont have to suffer like this. You dont have to waste your energy and time trying to cope with intrusive feelings that do not belong in your head and your heart. There are things you can do to treat them. All you need is will, professional help, and a little time.
