Hi. Thanks for your query. Read and understood your history and concerns and I hope this might have anything to do with your dog being infected with chlamydia. Noted your history of having a problem with urinary channels and after every sex with aching around the testicles and sperm to appear began to get yellow also to strengthen the penis and an erection not have to quickly. This history is suggestive of the following: - Pain in the testicles after every sex may be due to: - Blockage at the vas or epididymis. - Muscular pains referred to the testis due to strong act of sex. The sperms/ semen appears yellow after it comes out due to its interaction with air ans this is normal in most of the people. Another problem you are facing looks to be erectile dysfunction and premature ejaculation. Both the problems are usually related to psychological problems or the stress and anxiety. Hence the treatment of the anxiety and/or stress can improve on both the functions well. I hope this answer helps you.
