Did not know Hong Kong had a DNA test for men. I wish they would get the US and UK medical community to provide such a test.
Your doctor is not correct.

"Low-risk" types of HPV
There are about 12 types of HPV that are called "low risk" because they cannot cause cervical cancer. They can, however, cause genital warts or very minor cell changes on the cervix. These low-risk types of HPV are known by the numbers 6, 11, 40, 42, 43, 44, 53, 54, 61, 72, 73 and 81. Types 6 and 11 – which are linked to about 90 percent of genital warts – are the most common.
As you can see, strain 54 can cause genital warts. Average time is 2-8 months past exposure. The virus never leaves the body. You may be non-infectious now. But no one knows for how long. 90% never become infectious again. And the vaccine is only to prevent you from getting more strains. It has no impact on the strain that you currently have. Get it if you are 26 or under.
You can have sex with your wife to produce offspring and its safer to do this without any warts. That you had no warts after 3 months is a good sign. But if you want someone to tell you that you will never get a wart years/decades from now, that won't happen. 50% of infected people do not get any warts. No one knows why.
